abstract

High momentum transfer electrodisintegration of polarized and unpolarized deuterium targets, $d(e,e'p)n$ is studied. We show that the importance of final state interactions-FSI, occuring when a knocked out nucleon interacts with the other nucleon, depends strongly on the momentum of the spectator nucleon. In particular, these FSI occur when the essential contributions to the scattering amplitude arise from internucleon distances $\sim 1.5~fm$. But the absorption of the high momentum $\gamma^*$ may produce a point like configuration, which evolves with time. In this case, the final state interactions probe the point like configuration at the early stage of its evolution. The result is that significant color transparency effects, which can either enhance or suppress computed cross sections, are predicted to occur for $\sim 4 GeV^2 \ge Q^2\leq~10~(GeV/c)^2$.

Color transparency in $\bar p d \to \pi^- \pi^0 p$ reaction

nucl-th · 2019-09-01 · conditional · novelty 6.0

A model calculation predicts that color transparency strongly modifies the nuclear transparency ratio in \bar p d -> pi- pi0 p and that PANDA can observe this with modest statistics.
