Title: Polarization transfer in the 4He(e,e'p)3H reaction at Q2 = 0.8 and 1.3 (GeV/c)2

Abstract

Here, proton recoil polarization was measured in the quasielastic 4He(e,e'p)3H reaction at Q2 = 0.8 (GeV/c)2 and 1.3 (GeV/c)2 with unprecedented precision. The polarization-transfer coefficients are found to differ from those of the 1H(e,e'p) reaction, contradicting a relativistic distorted-wave approximation, and favoring either the inclusion of medium-modified proton form factors predicted by the quark-meson coupling model or a spin-dependent charge-exchange final-state interaction. For the first time, the polarization-transfer ratio is studied as a function of the virtuality of the proton.
