Supervisor’s research interests

Investigations in high energy heavy ion physics on the base of the data taking and analysis of ALICE experiment at the LHC at CERN.

Research highlights

ALICE (A Large Ion Collider Experiment) is a heavy-ion detector on the Large Hadron Collider (LHC) at CERN. It is designed to study the physics of strongly interacting matter at extreme energy densities in proton-proton and heavy ion collisions, where a phase of matter referred to as a quark-gluon plasma is formed.
The first observation of Σ0 and anti- Σ0 hyperons in proton-proton collisions at LHC with ALICE allows one its detailed analysis and simulations in proton-proton and lead-lead collisions on the base of ALICE data accumulated in 2010-2018.

Another topic is connected with the search and investigations of hyper-nuclei, i.e. nuclei with non-zero strangeness, produced at the LHC energies, service work and participation in data taking in the ALICE experiment in the next running period. Research is based on analysis of huge amount of data recorded by the ALICE experiment from proton-proton, proton-lead and lead-lead collisions at LHC.
During my work in the ALICE experiment at CERN since 2010 I supervised several master and Ph.D. students from Germany, Russia, South Korea and USA. The results of my research have been published in several ALICE papers.
