Nuclear Attenuation of Fast Hadrons Produced in Charged-Current Neutrino and Antineutrino Interactions in Neon

TL;DR

This paper investigates how fast hadrons produced in charged-current neutrino and antineutrino interactions are attenuated in neon compared to hydrogen, providing insights into hadron formation length and quark cross-sections.

Contribution

It presents experimental measurements of hadron attenuation in neon, supporting the constituent formation length model over the yo-yo model and estimating quark cross-sections.

Findings

Fast-hadron production is attenuated in neon relative to hydrogen.

Results favor the constituent formation length model.

Estimated quark cross-section is around 3 mb.

Abstract

The production of hadrons in charged-current (anti)neutrino interactions is studied with the bubble chamber BEBC exposed ot the CERN (anti)neutrino wide-band beam. Fast-hadron production in a neon target is found to be attennuated as compared to that in a hydrogen target. This feature is discussed within the theoretical models based on the idea of a hadron formation length. The experimental results favour the `constituent' over the `yo-yo' length concept, and suggest a quark cross-section in the order of 3mb.
