Description
The forward neutron production in the ep collisions at 300 GeV measured by the H1 and ZEUS Collaborations at DESY has been used to estimate the total probability for the proton fluctuation into nπ+ and pπ0. The probability found is on the order of the 30%. This number is compared with the numbers of obtained for the probability of quark fluctuation into π+ from several alternative DIS processes (Gottfried sum rule, polarized structure function) and the axial-vector coupling constant, where the pion fluctuation is believed to play an important role.
