Abstract

In this study, the proton is taken as an ensemble of quark-gluon Fock states. Using the principle of detailed balance, the probabilities of finding every Fock states of the proton are obtained without any parameter. A new origin of the light flavor sea quark asymmetry, i.e., u \not= d, is given as a pure statistical effect. It is found that d-u ≈ 0.124, which is in surprisingly agreement with the experimental observation.
