    "abstract": "The semi-inclusive cross section for producing slow protons in charged\ncurrent deep inelastic (anti-) neutrino scattering on protons and neutrons is\ncalculated as a function of the Bjorken $x$ and the proton momentum. The\nstandard hadronization models based upon the colour neutralization mechanism\nappear to underestimate the rate of slow proton production on hydrogen. The\npresence of the virtual mesons (pions) in the nucleon leads to an additional\nmechanism for proton production, referred to as spectator process. It is found\nthat at low proton momenta both mechanisms compete, whereas the spectator\nmechanism dominates at very small momenta, while the color neutralization\nmechanism dominates at momenta larger than 1-2 \\, GeV$/c$. The results of the\ncalculations are compared with the CERN bubble chamber (BEBC) data. The\nspectator model predicts a sharp increase of the semi-inclusive cross section\nat small $x$ due to the sea quarks in virtual mesons.",
