A study of the nuclear-medium influence on transverse momentum of hadrons produced in deep-inelastic neutrino scattering

摘要

The influence of nuclear effects on the transverse momentum (p(T)) of neutrino-produced hadrons is investigated using the data obtained with the SKAT propane-freon bubble chamber irradiated in the neutrino beam (with E-v = 3-30 GeV) at the Serpukhov accelerator. It has been observed that the nuclear effects cause an enhancement of < p(T)(2)> of hadrons produced in the target fragmentation region at low T invariant mass of the hadronic system (2 < W < 4 GeV) and at low energies transferred to the hadrons (2 < v < 9 GeV). At higher W and v, no influence of nuclear effects on < p(T)(2)> is observed. Measurement T results are compared with predictions of a simple model, incorporating secondary intranuclear interactions of hadrons, which qualitatively reproduces the main features of the data.
