Nuclear attenuation of three-hadron systems in neutrino-induced reactions

TL;DR

This study investigates how three-hadron systems are attenuated in neutrino-induced reactions within nuclei, revealing energy-dependent attenuation patterns and minimal correlation effects, and compares findings with quark string fragmentation models.

Contribution

First experimental analysis of nuclear attenuation of three-hadron systems in neutrino reactions using SKAT bubble chamber data.

Findings

Strong attenuation (R_3 ~ 0.6) for systems with high energy fraction

Minimal role of correlation effects in attenuation

Data compared with quark string fragmentation model predictions

Abstract

For the first time, the nuclear attenuation of three hadron systems is studied in neutrino-induced reactions using the data obtained with SKAT bubble chamber. The strongest attenuation (R_3 ~ 0.6) is observed for a system carrying an overwhelming fraction of the current quark energy, as well as for a system with the smallest effective mass. An indication is obtained that the correlation effects in the nuclear attenuation play only a minor role. The experimental data are compared with predictions of the quark string fragmentation model.
