# Performance studies of anisotropic flow with MPD at NICA

## TL;DR

This paper evaluates the MPD detector's capability to measure anisotropic flow in heavy-ion collisions at NICA energies through Monte Carlo simulations, focusing on systematic biases and detector effects.

## Contribution

It provides a comprehensive simulation-based assessment of MPD's performance for anisotropic flow measurements, including systematic bias analysis and detector non-uniformity effects.

## Key findings

- MPD can effectively measure directed and elliptic flow of charged hadrons.
- Systematic biases depend on detector subsystem configurations.
- Detector azimuthal non-uniformity influences flow measurement accuracy.

## Abstract

The Multi-Purpose Detector (MPD) at NICA collider has a substantial discovery potential concerning the exploration of the QCD phase diagram in the region of high net-baryon densities and moderate temperatures. The anisotropic transverse flow is one of the key observables to study the properties of dense matter created in heavy-ion collisions. The MPD performance for anisotropic flow measurements is studied with Monte-Carlo simulations of gold ions at NICA energies $\sqrt{s_{NN}}=4-11$ GeV using different heavy-ion event generators. Different combinations of the MPD detector subsystems are used to investigate the possible systematic biases in flow measurements, and to study effects of detector azimuthal non-uniformity. The resulting performance of the MPD for flow measurements is demonstrated for directed and elliptic flow of identified charged hadrons as a function of rapidity and transverse momentum in different centrality classes.
