文摘

In order to obtain information about the polarized strange quark distribution, we studied the semi-inclusive Λ_c⁺/Λ¯_c⁺ production in neutrino and polarized proton collisions. We found that these reactions are effective to clearly extract the polarization of strange quark by measuring the spin correlation between the target proton and the produced Λ_c⁺/Λ¯_c⁺ baryon.
