1 F2 and R in Deuterium and Nuclei Phase II (E06 009/E04 001) M. Eric Christy Hampton University Hall C Users Meeting Jan 26, 2007
2 E & E Physics FL, F1, F2 Fundamental Structure Function Measurements on Deuterium and Nuclei Structure Function Moments Lattice QCD comparisons Singlet and non-singlet distribution functions from deuteron and proton Support Broad Range of Deuteron Physics Elastic form factors BONUS neutron structure functions Input to extract spin structure functions from asymmetry measurements. Important input for neutrino physics Quark-hadron duality studies
3 Inclusive e + A e + X Scattering Rosenbluth Separation Technique: dσ dω de ' = Γ (σ T + εσ L ) Where: Γ = flux of transversely polarized virtual photons ε = relative longitudinal polarization σl FL R= = σ T 2xF1 FL = (1 + 4M 2 x 2 Q longitudinal 2 Transverse ) F2 2 xf1 m Ix Ed
4 Reproduce successful precision proton L/T separations. E performed 195 separations!
5 Global Survey of Longitudinal Strength in the Nucleon Resonance Region for Deuterium and Nuclei Q2 x W2 = 4 GeV2 W2 = Wπ pion threshold Essentially NO L/T separated data exist in the resonance region currently!
6 FL sensitive to gluon distributions.. Nucleon structure composed of singlet (gluons, sea) and non singlet (valence) distributions At moderate x (~ 0.3), singlet comparable to non singlet Large uncertainties on singlet distribution in structure function measurements, comes from (small) scaling violations in F2 FL is directly sensitive to glue!
7 (2F2p F2D)dx yields non singlet distribution Q2 evolution is simpler for the non-singlet (reduced number of splitting functions) Assuming a charge-symmetric sea, p-n isolates the nonsinglet Need to pin down non-singlet (p-n) to extract singlet (FL)..highly precise deuteron data - due to the above aspects are forming a conditio sine qua non for any real precision test of QCD. Johannes Bluemlein For similar reasons (non singlet calculations), p n moments are now available from lattice QCD at Q2 = 4 GeV2! F2 moments Detmold et al Dolgov et al. Gockeler Niculescu et al et al (hep ph/ ) n= / / n= / / Lattice QCD calculations experiment
8 Calculated on the lattice at Q2 = 4 GeV2 Well understood in QCD Operator Product Expansion For proton, n= 2 F2 moment = / For deuteron, n=2 F2 moment / nucleon = /0.008 In the difference, uncertainties in R matter! Moreover, can t even obtain FL moments really missing resonance region data! percentage contribution of resonance region to total moment (from proton moment data): Q2 (GeV2) F1 (n=2) F1 (n=4) FL (n=2) FL (n=4) % 91% 48% 89% % 64% 21% 64% % 49% 13% 52%
9 BONUS: NEUTRON cross sections via spectator tagging e Change in F2 with R spectator tagged in radial TPC p n Uncertainty in R introduces ~5% uncertainty true for all F2 extractions from cross sections (CLAS deuterium as well as BONUS) to CLAS
10 BoNuS combined with inclusive deuterium => help pin down nuclear corrections with BoNuS => correct L/T separated deuterium structure functions to get out neutron L/T SFs!
11 Neutrino Oscillations (same as JLab!) m2 ~ E / L, requires E in few GeV range Input for neutrino cross section models, needed for new generation of oscillation experiments around the world Jlab measurements can provide input on vector couplings Resonance region is a major contribution!
12 Form Factors for Free Jlab E measurements confirm SLAC hydrogen Rosenbluth results for GEp/GMp! Discrepency from PT results now ascribed to radiative 2-photon effects 2-photon effects on GEn should be larger than proton Blunden, Tjon, Melnitchuk, Phys.Rev. C72 (2005) (Rosenbluth measurements could result in GEn2 < 0?)
13 Preliminary Phase I Cross Sections The curves are from a fit to other Hall C Deuterium data (largely at higher Q2, all not L/T separated).
14 Phase-I Carbon Cross Sections for L/T εp= εδ = Separations (Q2 ~ 2) εp= εp = εδ = εδ = Need Phase II data to supply additional epsilon points, even for Q2 < 2.5.
15 L/T Separation Data: Targets: D, C, Al, Fe - Final uncertainties 1.6 % pt-pt in ε (2% normalization) - essentially, duplicate proton data set. Phase I kinematics (Jan '05) Proposed Phase II kinematics L/T separations where multiple energies.
16 projected from hydrogen current deuterium No L/T separated resonance region (large x) data on deuterium currently (little on heavier targets) Impossible to extract high precision moments After phase II data! Moments available Compare to lattice FL to access singlet
17 Issues during Phase I Low HMS hodoscope efficiencies Hodoscope refurbishment - see talk by Vardan Tadevosyan Problems setting and locking hms dipole New HMS controls - see talk by Steve Lassiter Thick HMS exit window (20 mil Ti)... large multiple scattering at low E' -> serious reconstruction issues! New Al exit window installed.
18 Additional Requirements Stable Beam - position and energy Stable BCMs High trigger efficiencies Veto pions with Cerenkov Stable magnet Fields
