Updated Trends in Neutrino-induced hadron production

TL;DR

This paper reanalyzes neutrino-induced hadron production data, comparing new fitting functions like shifted Gompertz and Weibull to traditional models, and examines how moments depend on target size, offering fresh insights into multiplicity distributions.

Contribution

It introduces alternative fitting functions for multiplicity distributions in neutrino interactions and analyzes their effectiveness compared to traditional models, with a focus on target size dependence.

Findings

Shifted Gompertz and Weibull functions effectively fit multiplicity distributions.

Moments of distributions depend on the target size.

Comparison shows new functions can outperform traditional models.

Abstract

With four different type of neutrino-induced interactions, we considered to investigate and reanalyse the KNO scaling in modified multiplicity distributions from a different perspective. In an attempt of first of its kind, we propose alternate fitting function to parameterise the distribution than the most widely adopted Slattery's function and compare it with yet another form. We propose the shifted Gompertz and Weibull functions as the fitting functions and compare their potency for the most conventional form of Slattery's function. In addition the analysis of the data by evaluating the central moments and factorial moments, we show the dependence of moments on the target size.
