Bose-Einstein Correlations in charged current muon-neutrino interactions in NOMAD

TL;DR

This paper investigates Bose-Einstein correlations in muon-neutrino interactions using NOMAD data, analyzing one- and two-dimensional effects and source shape differences.

Contribution

It provides the first detailed analysis of Bose-Einstein correlations in charged current muon-neutrino interactions with both one- and two-dimensional approaches.

Findings

Significant difference between transverse and longitudinal source sizes.

Bose-Einstein effect characterized using Goldhaber and Kopylov parametrizations.

Source shape varies between longitudinal and transverse dimensions.

Abstract

Bose-Einstein Correlations in one and two dimensions have been studied in charged current muon-neutrino interaction events collected with NOMAD. In one dimension the Bose-Einstein effect has been analyzed with the Goldhaber and the Kopylov parametrizations. The two-dimensional shape of the source has been investigated in the longitudinal co-moving frame. A significant difference between the transverse and the longitudinal sizes is observed.
