RECENT RESULTS ON MUON-NUCLEUS SCATTERING FROM THE E665 EXPERIMENT

摘要

Nuclear shadowing and diffractive scattering are measured in the interaction of muons on different targets. The size of the shadowing effect and the cross section for coherent diffractive production exhibit a similar dependence on xgj and the atomic mass A, suggesting a close relation between the two. The nuclear trans-parency for incoherent diffractive production of p(770) mesons increases with Q2, which may be interpreted as evidence for the onset of color transparency.
