A study of the double hadron neutrinoproduction on nuclei

TL;DR

This paper investigates how the nuclear medium affects double hadron production in neutrino interactions, revealing that nuclear attenuation is more significant for closely paired hadrons, and compares data with a string fragmentation model.

Contribution

First experimental analysis of nuclear effects on dihadron production in neutrino interactions using SKAT data, with comparison to a theoretical model.

Findings

Nuclear attenuation is more pronounced for closely paired hadrons.

Data shows significant nuclear medium influence on dihadron yields.

Comparison with string fragmentation model supports observed attenuation patterns.

Abstract

The nuclear medium influence on the dihadron neutrinoproduction is investigated for the first time, using the data obtained with SKAT bubble chamber. An indication is obtained that the nuclear attenuation of the dihadron is more expressed for kinematically closest hadron pairs. The experimental data on the dihadron attenuation and on the ratio of the dihadron to single-hadron yields are compared with predictions of the two-scale string fragmentation model.
