On an effective mechanism of charm particle production in neutrino and antineutrino beams

The effective mechanism governing the creation of charm particles in neutrino and antineutrino beams is shown; it consists in the formation of the charm virtual vector F* meson at the weak peak νF*μ (without suppression of the Cabibbo angle), followed by strong rescattering of the F* meson by the nucleon. This ''diffraction'' mechanism should make the principal contribution to the cross section for creation of the charm particles in the neutrino experiment at energies of up to several hundred GeV. Charm particles are chiefly created at limited transfered momenta when mod[q2] is of the order of [Msub(F*)]2, and with equal cross-sections in the neutrino and antineutrino beams. (author)
