# Event Shape Sorting: prospects and femtoscopy applications

## TL;DR

This paper explores Event Shape Sorting as a novel method in femtoscopy, enabling detailed analysis of azimuthal correlations and anisotropies in hadron distributions, revealing features difficult to detect with traditional Event Shape Engineering.

## Contribution

It introduces Event Shape Sorting to femtoscopy, demonstrating its ability to identify complex azimuthal anisotropies and distinguish features not accessible by existing methods.

## Key findings

- Event Shape Sorting reveals azimuthal anisotropies of different orders.
- Correlation radii depend on azimuthal angle with observable anisotropies.
- Statistical fluctuations impact the effectiveness of event sorting.

## Abstract

We demonstrate the use of Event Shape Sorting in femtoscopy. The method allows to select events with similar distributions if hadrons in azimuthal angle. We show that also their correlation radii exhibit interesting dependence on azimuthal angle with anisotropies of different orders visible at the same time. We further demonstrate such features of the hadron distribution which can be hardly recognised by Event Shape Engineering, but shows up in Event Shape Sorting. Finally, the influence of statistical fluctuations on sorting is investigated.
