Event shape analysis in ultrarelativistic nuclear collisions

TL;DR

This paper introduces a new event shape analysis method in ultrarelativistic nuclear collisions that considers the entire azimuthal distribution, offering a more comprehensive and multiplicity-independent way to classify events.

Contribution

The novel approach utilizes the full azimuthal angle distribution for event sorting, improving upon traditional single-variable methods.

Findings

Provides a multiplicity-independent measure of event shape

Enhances event classification accuracy

Potential applications in femtoscopy and exclusive studies

Abstract

We present a novel method for sorting events. So far, single variables like flow vector magnitude were used for sorting events. Our approach takes into account the whole azimuthal angle distribution rather than a single variable. This method allows us to determine the good measure of the event shape, providing a multiplicity-independent insight. We discuss the advantages and disadvantages of this approach, the possible usage in femtoscopy, and other more exclusive experimental studies.
