论文摘要

模型在包括核结合和外壳效应的模型中检查了对异性效应和费米运动产生的核核EMC效应的相对贡献。与期望相反,费米运动的作用淹没了短距离相关性(SRC)中核子的外壳效应,质疑SRCS与EMC效应之间假设的因果关系。

The relative contributions to the valence nuclear EMC effect in the deuteron arising from off-shell effects and Fermi motion are examined in models which include nuclear binding and off-shell effects. Contrary to expectations, the effect of Fermi motion overwhelms the off-shell effects for nucleons in short-range correlations (SRCs), calling into question the hypothesized causal connection between SRCs and the EMC effect.
