A joint scientific seminar organized by the Faculties of Physics and Mechanics and Mathematics at Baku State University (BSU) was held online, bringing together researchers and students for an engaging discussion on advanced topics in particle physics.

The seminar featured a presentation by Professor Elshen Veliyev of Kocaeli University, a distinguished BSU alumnus, who delivered a report titled "Study of Hadron Parameters at Temperatures Close to the Phase Transition of Quark-Gluon Plasma."

In his presentation, Professor Veliyev explained that under conditions of extremely high temperature and density, ordinary matter transitions into a new state known as quark-gluon plasma — a phase in which quarks and gluons, the fundamental constituents of hadrons, are no longer confined. This state of matter, believed to have existed microseconds after the Big Bang, has been experimentally confirmed through high-energy collisions at facilities such as the European Organization for Nuclear Research (CERN) in Switzerland and the Brookhaven National Laboratory in the United States.

The seminar concluded with an interactive discussion, where participants explored the implications of quark-gluon plasma in theoretical physics and cosmology.
