Polarization Transfer In The H-2((E)Over-Right-Arrow, E(')(P)Over-Right-Arrow)N Reaction Up To Q(2)=1.61 (Gev/C)(2)

The recoil proton polarization was measured in the H-2(e,e(')p)n reaction in Hall A of the Thomas Jefferson National Accelerator Facility. The electron kinematics were centered on the quasielastic peak (x(Bj)approximate to 1) and included three values of the squared four-momentum transfer, Q(2)=0.43,1.00 and 1.61 (GeV/c)(2). For Q(2)=0.43 and 1.61 (GeV/c)(2), the missing momentum, p(m), was centered at zero, whereas for Q(2)=1.00 (GeV/c)(2) two values of p(m) were chosen: 0 and 174 MeV/c. At low p(m), the Q(2) dependence of the longitudinal polarization, P-z('), is not well described by a state-of-the-art calculation. Further, at higher p(m), a 3.5 sigma discrepancy was observed in the transverse polarization, P-x('). Understanding the origin of these discrepancies is important to confidently extract the neutron electric form factor from the analogous H-2(e,e(')n)p experiment.
