7 Four Different Approaches Cosmology: CMB (Relic Density, Baryon Acoustic Oscillations (BAO)), Large Scale Structure, Big Bang Nucleosynthesis (BBN), Strong and Weak Gravitational Lensing, Bullet Cluster, distant Type Ia supernovae,... Direct Detection (Terrestrial): DM scatter off nuclei in terrestrial detectors - recoil energy spectrum Indirect Detection (Astrophysical): DM annihilation into SM particles (gamma rays, electron/positron, antimatter, neutrinos etc) at massive astrophysical objects, in Sun or Earth Production and detected indirectly as missing energy at LHC 7
8 Relic Density 8
9 Relic Density of a Particle Species A particle species in the early Universe has to have a sufficiently fast interaction rate to maintain its thermal equilibrium. A particle will decouple when its annihilation rate falls below the Hubble expansion rate of the Universe. The abundance of a heavy particle is governed by the Boltzmann eq a 3 d(na3 ) dt = dn dt +3Hn = σv n 2 eq n 2 Non-relativistic limit: SM + SM χ + χ χ + χ SM + SM n eq = g mt 2π 3/2 e m/t, m T σv = a + bv 2 = a +6 b x, x m T v 1 a and b are S and P wave contributions 9

24 Constraints on Effective Interactions Our approach (adopted by other several groups as well): (1) assumption: the connector sector must be heavy and integrated out (2) DM can be (real/complex) scalar or (Majorana/ Dirac) fermionic; vector DM not considered (3) effective interaction of WIMP DM with SM particles (4) model independent study for a large class of models Direct detection experiments can place upper limits on cross sections hence lower limits on effective scales Λ 24

27 Indirect Detection 27
28 Indirect Detection Indirect signals from DM annihilation into gamma rays (line or continuum), neutrinos, antimatter like positrons and antiproton,... Ambiguous due to possible astrophysical sources like pulsars, cosmic rays,... If the final states are charged (positron, antiproton, etc), predictions depend on parameters in propagation model, since they can lose energy while traversing in the cosmic medium Gamma rays and neutrinos have lesser propagation effects Pamela, Fermi-LAT, AMS-02, HESS, Veritas,... Neutrino telescopes: IceCube, ANTARES,... 28

46 No evidence of DM from particle physics yet! All evidences are from heaven so far! (I know. We can t ignore DAMA/LIBRA and CoGeNT yet.) Summary Particle DM is definitely needed at various scales (1) largest cosmological scales (WMAP), (2) galaxy cluster scales (Coma Cluster), (3) dwarf galaxies, (4) Bullet Clusters,... Three important complementary particle DM probes: direct detection, indirect detection, and collider. No lack of theoretical ideas for particle DM candidates. Popular model like MSSM is highly constrained now. Effective DM interaction -- model independent approach but has limitations. Combing results from different experiments provide important constraints on DM models or effective interactions. We live in exciting time!! Stay tuned for new results from LHC8 and AMS
