“…In this section, we explain the relativistic impulse approximation (RIA) [46] whose results are compared with those of INC. The RIA calculation in this paper is the standard one in the quasifree region, and is essentially the same as Iijima et al [5].…”

In a framework of intranuclear cascade (INC) type calculation, we study a momentum spectrum in reactions (K − , K + ) at a beam momentum of 1.65 GeV/c. INC model calculations are compared with the relativistic impulse approximation (RIA) calculations to perform the detailed study of the reaction mechanism. We find that the INC model can reproduce the experimental data on various targets. Especially, in the low-momentum region, the forward-angle cross sections of the (K − , K + ) reaction on from light to heavy targets are consistently explained with the two-step strangeness exchange and production processes with various intermediate mesons, and φ, a 0 and f 0 productions and their decay into K + K − . In the two-step processes, inclusion of meson and hyperon resonances is found to be essential.

“…Thus as a first step, we neglect some other effects such as the influence of the potential effect between hadrons. We will also compare the results of the INC spectrum with the onestep process spectrum in the relativistic impulse approximation (RIA) model [46] to study the reaction (K − , K + ) in detail.…”

“…The question arises as to how sensitive polarization transfer observables are to nuclear distortion and, in particular, to different optical potential parameter sets. Current qualitative arguments suggest that, since polarization transfer observables are ratios of polarized cross sections, distortion effects on the scattering wave functions effectively cancel, and hence simple plane wave models (ignoring nuclear distortion) should be appropriate for studying polarization phenomena [10,11]. Recently we demonstrated that, contrary to intuition, the ( p, 2p) analyzing power is extremely sensitive to nuclear distortion within the context of the relativistic DWIA [5].…”

“…They noted that the shape of the quasifree spectrum was target dependent, indicating the need for caution in any use of a "universal" model for quasifree scattering. It was also found that analyzing powers were decreased with respect to the free N-N scattering values for 12 C at both incident energies, and for 54 Fe at 290 MeV, as predicted by [237].…”

“…They noted that only the analyzing power shows an unambiguous relativistic signature at the highest energy, a fact pointed out earlier by Horowitz and Murdock [237]. They also pointed out that the polarization transfer observable, Dnn' , was extremely sensitive to whether the pion-nucleon vertex was taken as pseudoscalar or pseudovector, particularly for incident energies under 200 MeV, and that this sensitivity should not be masked by the effect of spin-orbit distortions nor any "effective mass" effect.…”
