EMC effect in semi-inclusive deep-inelastic scattering process

Abstract

By considering the $x$-dependence of ${\pi }^{+}$, ${\pi }^{-}$, $K^{+}$, $K^{-}$, $\Lambda$, $\bar{\Lambda }$, $p$, $\bar{p}$ 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 $({\bar{\Lambda }}^A/{\Lambda }^A)/({\bar{\Lambda }}^D/{\Lambda }^D)$ 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.
