Abstract

The NICA (Nuclotron-based Ion Collider fAcility) is the new international research facility under construction at the Joint Institute for Nuclear Research (JINR) in Dubna. The main targets of the facility are the following: 1) study of hot and dense baryonic matter at the energy range of the maximum baryonic density; 2) investigation of nucleon spin structure and polarization phenomena; 3) development of JINR accelerator facility for high energy physics research based on the new collider of relativistic ions from protons to gold and polarized protons and deuterons as well with the maximum collision energy of √SNN ~11GeV (Au79+ +Au79+) and ~ 27 GeV (p+p). Two collider detector setups MPD and SPD are foreseen. The setup BM@N (Baryonic Matter at Nuclotron) is commissioned for data taken at the existing Nuclotron beam fixed target area. The MPD construction is in progress whereas the SPD is still at the beginning design stage. An average luminosity of the collider is expected at the level of 1027 cm-2 s-1 for Au79+ and 1032 cm-2 s-1 for polarized protons at 27 GeV. The status of NICA design and construction work is briefly described below.

Highlights

  • Research (JINR) since 2010 [1]

  • The NICA research domain is attractive as possible domain of phase transitions searching.The study of the nucleon spin content and polarization phenomena in the collisions of polarized protons and light polarized ions introduce a target of the further research at NICA

  • Status report on the NICA design and construction is presented regularly at different international meetings and conferences including the ICNFP serial [6], we limited this paper by brief description of some recent results

Summary

Introduction

Research (JINR) since 2010 [1]. The study of hot and dense baryonic matter should shed light on: in-medium properties of hadrons and the nuclear matter equation of state (EOS); the onset of deconfinement (OD) and/or chiral symmetry restoration (CSR); phase transition (PT), mixed interactions phase and the (LPV)∼[2,3,4,5]. The NICA construction is progressing step-by-step foresees an essential development of the accelerator facility and construction of the new spectrometer BM@N in order to start. The fixed target experiments with heavy ion beams extracted from modernized Nuclotron in 2017 and to prepare the MPD start version for commissioning by 2021.
