Title: Influence of relativistic dynamics and density-dependent corrections on the induced polarization and analyzing power for exclusive 1s{sub 1/2} proton knockout in {sup 12}C

Abstract

Induced polarization and analyzing power data for exclusive proton-induced proton knockout from the 1s{sub 1/2}-state in {sup 12}C - at incident energies of 392 MeV and 1 GeV and for kinematics corresponding to zero recoil momentum - are studied within the framework of both relativistic and nonrelativistic distorted wave models based on the impulse approximation. We also study to which extent relativistic dynamical effects can be simulated in the nonrelativistic Schroedinger-equation-based distorted wave model via the introduction of effective nucleon mass corrections (within the context of the Walecka model of quantum hadrodynamics) to the nucleon-nucleon (NN) scattering matrix. A quantitative description of the data is achieved by invoking density-dependent corrections to the NN amplitudes within the framework of our relativistic distorted wave model.
