主  题:strange and antistrange quark distributions nucleon meson cloud model 

摘      要:The difference between the strange and antistrange quark distributions,δs(x) = s(x) ˉs(x),and the combination of light quark sea and strange quark sea,Δ(x) =ˉ d(x) + uˉ(x) s(x) ˉs(x),are originated from non-perturbative processes and can be calculated using non-perturbative models of the *** report calculations of δs(x) and Δ(x) using the meson cloud *** our calculations of Δ(x) with relatively well known light antiquark distributions obtained from global analysis of available experimental data,we estimate the total strange sea distributions of the nucleon.
