Parton Distribution of Proton in a Simple Statistical Model
Yong-Jun Zhang, Bing-Song Zou, Li-Ming Yang
Abstract
Taking proton as an ensemble of quark-gluon Fock states and using the principle of detailed balance, we construct a simple statistical model for parton distribution of proton. The recent observed Bjorken-x dependent light flavor sea quark asymmetry d(x)-u(x) can be well reproduced by Monte Carlo simulation as a pure statistical effect.
