| Popis: |
For the first time, the total yield and inclusive spectra of the $\Delta^{++}(1232)$isobar are measured in $\nu p$ and $\nu n$ charged-current interactions. An indication is obtained that the $\Delta^{++}(1232)$ production mainly results from the neutrino scattering on the valence d- quark of the target nucleon. The total yield of $\Delta^{++}(1232)$ in $\nu p$ interactions is compatible with that measured in hadronic interactions of the same net charge and net baryonic number. The yield of $\Delta^{++}(1232)$ in $\nu n$ interactions is significantly suppressed as compared to the case of the proton target. The form of the squared transverse momentum distributions, both in $\nu p$ and $\nu n$ interactions, is found to be compatible with the available data on the neutrinoproduction of $\Lambda$ hyperon. The experimental data are compared with the LEPTO6.5 model predictions. |
