Item Open Access Polarization Transfer in the He-4((e)over-right-arrow, e '(p)over-right-arrow)H-3 Reaction at Q(2)=0.8 and 1.3 (GeV/c)(2)(2010) Paolone, M; Malace, SP; Strauch, S; Albayrak, I; Arrington, J; Berman, BL; Brash, EJ; Briscoe, B; Camsonne, A; Chen, J-P; Christy, ME; Chudakov, E; Cisbani, E; Craver, B; Cusanno, F; Ent, R; Garibaldi, F; Gilman, R; Glamazdin, O; Glister, J; Higinbotham, DW; Hyde-Wright, CE; Ilieva, Y; de Jager, CW; Jiang, X; Jones, MK; Keppel, CE; Khrosinkova, E; Kuchina, E; Kumbartzki, G; Lee, B; Lindgren, R; Margaziotis, DJ; Meekins, D; Michaels, R; Park, K; Pentchev, L; Perdrisat, CF; Piasetzky, E; Punjabi, VA; Puckett, AJR; Qian, X; Qiang, Y; Ransome, RD; Saha, A; Sarty, AJ; Schulte, E; Solvignon, P; Subedi, RR; Tang, L; Tedeschi, D; Tvaskis, V; Udias, JM; Ulmer, PE; Vignote, JR; Wesselmann, FR; Wojtsekhowski, B; Zhan, X; E03-104 CollaborationProton recoil polarization was measured in the quasielastic He-4((e) over right arrow, e '(p) over right arrow)H-3 reaction at Q(2) = 0.8 and 1.3 (GeV/c)(2) with unprecedented precision. The polarization-transfer coefficients are found to differ from those of the H-1((e) over right arrow, e '(p) over right arrow) 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.
