半包容深度非弹性散射过程中的EMC效应

EMC effect in semi-inclusive deep-inelastic scattering process

Baogui Lu, Bo-Qiang Ma

摘要:

本文考虑了带电轻子半包容深非弹性散射中$π^+$、$π^-$、$K^+$、$K^-$、$Λ$、$\barΛ$、$p$、$\bar{p}$强子产生对$x$的依赖性(以Fe为例)和氘D靶,%在$Q^2=5$ GeV $^2$,我们发现$(\barΛ^A/Λ^A)/(\barΛ^D/Λ^D)$和$({\bar{p}}^A/{p}^A)/({\bar{p}}^A/p^A)$是计算核海含量的理想方法,考虑到核EMC效应,不同的模型预测的结果不同。

英文摘要:

By considering the $x$-dependence of $π^+$, $π^-$, $K^+$, $K^-$, $Λ$, $\barΛ$, $p$, $\bar{p}$ hadron productions in charged lepton semi-inclusive deep inelastic scattering off nuclear target (using Fe as an example) and deuteron D target, % at $Q^2=5$ GeV$^2$, we find that $(\barΛ^A/Λ^A)/(\barΛ^D/Λ^D)$ and $({\bar{p}}^A/{p}^A)/({\bar{p}}^A/p^A)$ are ideal to figure out the nuclear sea content, which is predicted to be different by different models accounting for the nuclear EMC effect.
