- ПубликацияОткрытый доступPion femtoscopy in p+Au and Au+Au collisions at using transport approach(2020) Kuzina, E.; Khyzhniak, E. V.; Ermakov, N.; Nigmatkulov, G.; Alpatov, E.; Нигматкулов, Григорий Александрович; Алпатов, Егор Вячеславович© Published under licence by IOP Publishing Ltd.Correlation femtoscopy provides information about the space-Time structure and evolution of the fireball created in ultra-relativistic nucleus-nucleus collisions. The dependence of the femtoscopic radii on transverse pair momentum and charged particle multiplicity of an event reflects the mechanism of collective behavior. In this work, the femtoscopic radii of identical charged pions were calculated in the UrQMD model for Au+Au and p+Au collisions at and compared to each other at the same multiplicities. The physics implications of this comparison will be discussed.

The Multi-Purpose Detector (MPD) has been designed to operate at NICA and its components are currently in production. The detector is expected to be ready for data taking with the first beams from NICA. This document provides an overview of the landscape of the investigation of the QCD phase diagram in the region of maximum baryonic density, where NICA and MPD will be able to provide significant and unique input. It also provides a detailed description of the MPD set-up, including its various subsystems as well as its support and computing infrastructures. Selected performance studies for particular physics measurements at MPD are presented and discussed in the context of existing data and theoretical expectations. © 2022, The Author(s), under exclusive licence to Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature.
- ПубликацияОткрытый доступGlobal hyperon polarization in Au+Au collisions at √sNN = 27 GeV in the STAR experiment(2020) Alpatov, E.; Алпатов, Егор Вячеславович© 2020 Institute of Physics Publishing. All rights reserved.The Quark-Gluon Plasma (QGP), appearing in non-central nucleus-nucleus collisions is generated with large orbital angular momentum. Spin-orbit coupling aligns spin directions of produced particles with the system angular momentum, through the creation of local vorticity. Properties of hyperon weak decays lead to the way of measuring polarization, that reflects vorticity. The global polarization of Λ and Λ hyperons was measured for Au+Au collisions at √sNN = 7.7 - 200 GeV recorded with the STAR at the RHIC. However, different theoretical approaches are still in need of new experimental input to describe global polarization properly. That's why it is important to measure the global polarization of different particle species. In this paper, we will report new results of hyperon global polarization (PΛ+Λ and PΞ−+Ξ+) measurement via different methods for high-statistics Au+Au collisions at √sNN = 27 GeV.
