2 Review of Particle Physics: C. Caso et al. (Particle Data Group), European Physical Journal C3, (998) MINIMAL SUPERSYMMETRIC STANDARD MODEL ASSUMPTIONS All results shown below (except where stated otherwise) are based on the Minimal Supersymmetric Standard Model (MSSM) as described in the Note on Supersymmetry. This includes the assumption that R-parity is conserved. In addition the following assumptions are made in most cases: ) The (or e) is the lightest supersymmetric particle (LSP). ) m efl = m efr where e f L and e f R refer to the scalar partners of left-and right-handed fermions. Limits involving dierent assumptions either are identied with comments or are in the miscellaneous section. When needed, specic assumptions of the eigenstate content of neutralinos and charginos are indicated (use of the notation e (photino), e H (Higgsino), fw (w-ino), and e Z (z-ino) indicates the approximation of a pure state was made). (Lightest Neutralino) MASS LIMIT is likely to be the lightest supersymmetric particle (LSP). See also the, 3, 4 section below. We have divided the listings below into three sections: ) Accelerator limits for, ) Bounds on from dark matter searches, and 3) Other bounds on from astrophysics and cosmology. Accelerator limits for These papers generally exclude regions in the M { parameter plane based on accelerator experiments. Unless otherwise stated, these papers assume minimal supersymmetry and GUT relations (gaugino-mass unication condition). m 0 = m? m.

3 Review of Particle Physics: C. Caso et al. (Particle Data Group), European Physical Journal C3, (998) p ABREU 98 bound combines the chargino and neutralino searches at s=6, 7 with single-photon-production results at LEP- from ABREU 97J. The limit is based on the same assumptions as ALEXANDER 96J except m 0 = TeV. ACCIARRI 98F evaluates production cross sections and decay branching ratios within the MSSM, and includes in the analysis the eects of gaugino cascade decays. The limit is obtained for 0 <M < 000, < 500, and <tan < 40, but remains valid outside this domain. No dependence on the trilinear-coupling parameter A is found. The limit holds for all values of m 0 consistent with scalar lepton contraints. It improves to 4:6 for m e > 00. Data taken at p s = 30{7. 3 ACKERSTAFF 98L evaluates production cross sections and decay branching ratios within the MSSM, and includes in the analysis the eects of gaugino cascade decays. The bound is determined indirectly from the e+ and searches within the MSSM. The limit is obtained for 0 <M < 500, < 500 and tan >, but remains valid outside this domain. The limit holds for the smallest value of m 0 consistent with scalar lepton constraints (ACKERSTAFF 97H). It improves to 4:7 for m 0 = TeV. Data taken at p s=30{7. 4 ALEXANDER 96L bound for tan=35 is 6:0. 5 BUSKULIC 96A puts a lower limit on m from the negative search for neutralinos, charginos. The bound holds for m e > 00. A small region of (,M ) still allows m =0 if sneutrino is lighter. This analysis combines data from e + e? collisions at p s=9: and at 30{36. 6 ACCIARRI 95E limit for tan > is 0, and the bound disappears if tan. 7 ELLIS 97C uses constraints on, 0, and è production obtained by the LEP experiments from e + e? collisions at p s = 30{7. It assumes a universal mass m 0 for scalar leptons at the grand unication scale. 8 ABREU 96O searches for possible nal states of neutralino pairs produced in e + e? collisions at p s = 30{40. See their Fig. 3 for excluded regions in the (,M ) plane. 9 ACCIARRI 96F searches for possible nal states of neutralino pairs produced in e + e? collisions at p s= 30{40. See their Fig. 5 for excluded regions in the (,M ) plane. 0 ALEXANDER 96J bound is determined indirectly from the e and searches within MSSM. A universal scalar mass m 0 at the grand unication scale is assumed. The bound is for the smallest possible value of m 0 allowed by the LEP è, e mass limits. Branching fractions are calculated using minimal supergravity. The bound is for m? m >0. The limit improves to :4 for m 0 = TeV. Data taken at p s = 30{36. ACKERSTAFF 96C, using data from p s = 6, improves the limit for m 0 = TeV to 30:3. FRANKE 94 reanalyzed the LEP constraints on the neutralinos in the MSSM with an additional singlet. DECAMP 9 limit for tan > is m>3. 3 HEARTY 89 assumed pure e eigenstate and mel = m er. There is no limit for m e >58. Uses e + e?! e e. No GUT relation assumptions are made.

4 Review of Particle Physics: C. Caso et al. (Particle Data Group), European Physical Journal C3, (998) Bounds on from dark matter searches These papers generally exclude regions in the M { parameter plane assuming that is the dominant form of dark matter in the galactic halo. These limits are based on the lack of detection in laboratory experiments or by the absence of a signal in underground neturino detectors. The latter signal is expected if accumlates in the Sun or the Earth and annihilates into high-energy 's.

The analysis includes top radiative corrections on Higgs parameters and employs two dierent hypotheses for nucleon-higgs coupling. Eects of rescaling in the local neutralino density according to the neutralino relic abundance are taken into account. 8 BOTTINO 9 excluded a region in M? plane using upgoing muon data from Kamioka experiment, assuming that the dark matter surrounding us is composed of neutralinos and that the Higgs boson is not too heavy. 9 GELMINI 9 exclude a region in M? plane using dark matter searches. 0 KAMIONKOWSKI 9 excludes a region in the M { plane using IMB limit on upgoing muons originated by energetic neutrinos from neutralino annihilation in the sun, assuming that the dark matter is composed of neutralinos and that m H See Fig. 8 in the paper.

5 Review of Particle Physics: C. Caso et al. (Particle Data Group), European Physical Journal C3, (998) Other bounds on from astrophysics and cosmology Most of these papers generally exclude regions in the M { parameter plane by requiring that the contribution to the overall cosmological density is less than some maximal value to avoid overclosure of the Universe. Those not based on the cosmological density are indicated. Many of these papers also include LEP and/or other bounds.

6 Review of Particle Physics: C. Caso et al. (Particle Data Group), European Physical Journal C3, (998) 8 GRIFOLS 90 argues that SN987A data exclude a light photino (. MeV) if m eq < : TeV, m e < 0:83 TeV. 9 ELLIS 88B argues that the observed neutrino ux from SN 987A is inconsistent with a light photino if 60. m eq. :5 TeV. If m(higgsino) is O(00 ev) the same argument leads to limits on the ratio of the two Higgs v.e.v.'s. LAU 93 discusses possible relations of ELLIS 88B bounds. 30 KRAUSS 83 nds me not 30 ev to.5. KRAUSS 83 takes into account the gravitino decay. Find that limits depend strongly on reheated temperature. For example a new allowed region m e = 4{0 MeV exists if m gravitino <40 TeV. See gure., 3, 4 (Neutralinos) MASS LIMITS Neutralinos are unknown mixtures of photinos, z-inos, and neutral higgsinos (the supersymmetric partners of photons and of Z and Higgs bosons). The limits here apply only to, 3, and 4. is the lightest supersymmetric particle (LSP); see Mass Limits. It is not possible to quote rigorous mass limits because they are extremely model dependent; i.e. they depend on branching ratios of various decay modes, on the masses of decay products (e, e, eq, eg), and on the e mass exchanged in e + e?! i j. Often limits are given as contour plots in the m? m e plane vs other parameters. When specic assumptions are made, e.g, the neutralino is a pure photino (e), pure z-ino ( e Z), or pure neutral higgsino ( e H 0 ), the neutralinos will be labelled as such.

See their Fig. 5 for excluded region in the neutralino-chargino parameter space. Data taken at p s = 30{ BUSKULIC 95E looked for e + e?!, where decays via R-parity violating interaction into one neutrino and two opposite-charge leptons. The bound applies provided that B(Z! )> 3 0?5 3, being the nal state velocity. 65 BUSKULIC 95E looked for e + e?! e e, where e decays via R-parity violating interaction into one neutrino and two opposite-charge leptons. They extend the domain in the (m e,m e ) plane excluded by ACTON 93G to m e >0 /c (for m e =5 /c ) and to m e > /c (for m e <0 /c ). 66 ACTON 93G assume R-parity violation and decays e! ` ` (`= e or ). They exclude m e = 4{43 for m el <4, and m e = 7{30 for m el <00 (95% CL).

Assume e decays to photon + goldstino and search for acoplanar photons with large missing p T. 70 BALL 84 is FNAL beam dump experiment. Observed no e decay, where e's are expected to come from eg's produced at the target. Three possible e lifetimes are considered. Gluino decay to goldstino + gluon is also considered. 7 BEHREND 83 and BARTEL 84B look for events from e pair production. With supersymmetric breaking parameter d = (00 ) and m e = 40 the excluded regions at CL = 95% would be m e = 00 MeV { 3 for BEHREND 83 m e = 80 MeV { 8 for BARTEL 84B.

22 Review of Particle Physics: C. Caso et al. (Particle Data Group), European Physical Journal C3, (998) semileptonic decays of charginos produced in the cascade decays. The limit is derived for xed tan = 4:0, =?400, and m H + = 500, and with the cascade decays of the squarks and gluinos calculated within the framework of the Minimal Supergravity scenario. 69 ABACHI 95C assume ve degenerate squark avors with meql = m eqr. Sleptons are assumed to be heavier than squarks. The limits are derived for xed tan = :0 =?50, and m H + =500, and with the cascade decays of the squarks and gluinos calculated within the framework of the Minimal Supergravity scenario. The bounds are weakly sensitive to the three xed parameters for a large fraction of parameter space. No limit is given for m gluino > DATTA 97 argues that the squark mass bound by ABACHI 95C can be weakened by 0{0 if one relaxes the assumption of the universal scalar mass at the GUT-scale so that the e, in the squark cascade decays have dominant and invisible decays to e. 7 DERRICK 97 looked for lepton-number violating nal states via R-parity violating couplings 0 i j k L i Q j d k. When 0 k 0 i j k 6= 0, the process e u! e d k! `i u j is possible. When 0 j 0 i j k 6= 0, the process e d! eu j! `i d k is possible. 00% branching fraction eq! `j is assumed. The limit quoted here corresponds to et! q decay, with 0 =0:3. For dierent channels, limits are slightly better. See Table 6 in their paper. 7 HEWETT 97 reanalyzed the limits on possilbe resonances in di-jet mode (eq! q eg) from ALITTI 93 quoted in \Limits for Excited q (q ) from Single Production," ABE 96 in \SCALE LIMITS for Contact Interactions: (q q q q)," and unpublished CDF, D bounds. The bound applies to the gluino mass of 5, and improves for lighter gluino. The analysis has gluinos in parton distribution function. 73 TEREKHOV 97 improved the analysis of TEREKHOV 96 by including di-jet angular distributions in the analysis. 74 AID 96 looked for rst-generation squarks as s-channel resonances singly produced in e p collision via the R-parity violating coupling in the superpotential W =L Q d. The degeneracy of squarks Q e and d e is assumed. Eight dierent channels of possible squark decays are considered. 75 AID 96C used electron+jet events with missing energy and momentum to look for e q! e eq via neutralino exchange with decays into (e )(q ). See the paper for dependences on m e, m. 76 TEREKHOV 96 reanalyzed the limits on possible resonances in di-jet mode (eu! u eg) from ABE 95N quoted in \MASS LIMITS for g A (axigluon)." The bound applies only to the case with a light gluino. 77 ABE 95T looked for a cascade decay of ve degenerate squarks into which further decays into and a photon. No signal is observed. Limits vary widely depending on the choice of parameters. For =?40, tan = :5, and heavy gluinos, the range 50<m eq ()<0 is excluded at 90% CL. See the paper for details. 78 BUSKULIC 95E looked for Z! eq eq, where eq! q 0 and 0 decays via R-parity violating interactions into two leptons and a neutrino. 79 AHMED 94B looked for squarks as s-channel resonance in e p collision via R-parity violating coupling in the superpotential W = L Q d. The degeneracy of all squarks Q and d is assumed. The squarks decay dominantly via the same R-violating coupling into e q or q if &0:. For smaller, decay into photino is assumed which subsequently decays into e q q, and the bound depends on m e. See paper for excluded region on (m eq,) plane. 80 ADRIANI 93M limit from?(z)< 35: MeV and assumes meql m eqr. Page 86 Created: 6//998 5:9
