Abstract

BM@N (Baryonic Matter at Nuclotron) is the first experiment to be realized at the accelerator complex of NICA-Nuclotron. The aim of the BM@N experiment is to study interactions of relativistic heavy ion beams with fixed targets. The BM@N setup, results of Monte Carlo simulations, the BM@N experimental program and results of technical runs are presented.

Highlights

  • Relativistic heavy ion collisions provide an unique opportunity to study nuclear matter at extreme density and temperature

  • The technical runs of the Baryonic Matter at Nuclotron (BM@N) detector were performed with the deuteron beam in December 2016 and with the carbon beam in March 2017

  • The BM@N experiment is in the starting phase of its operation and has recorded first experimental data

Summary

Introduction

Relativistic heavy ion collisions provide an unique opportunity to study nuclear matter at extreme density and temperature. At even higher temperatures or densities hadrons melt, and the constituents, quarks and gluons, form a new phase, the Quark-Gluon Plasma (QGP). At these extreme conditions the following features (amongst others) can be studied: the equation-of-state (EoS) of strongly interacting matter at high temperatures and high net-baryon densities; the microscopic structure of strongly interacting matter in dependence on temperature and baryon density; the in-medium modifications of hadrons which might provide information on the onset of chiral symmetry restoration. Theoretical models, predict different characteristics of the created matter. New experimental data with high resolution and statistics are needed in order to disentangle different theoretical predictions [1]
