Krzysztof Kutak is a theoretical particle physicist based at Institute of Nuclear Physics, Polish Academy of Sciences, where he leads the Department of Particle Theory. His research interests center on particle physics, especially on Quantum Chromodynamics (QCD), a theory describing properties of the basic building blocks of hadronic matter, i.e. quarks and gluons. This theory is also a basic tool which is used to set up initial conditions for collisions of protons and ions at colliders like the Large Hadron Collider. My main interest at the moment is the study of high-energy behavior of cross section in high-density QCD as studied in Large Hadron Collider at CERN and will be studied further at the US-based Electron Ion Collider (EIC). In particular the interesting feature of gluon density at high energies is gluon saturation, i.e. a state of a system of gluons where the gluon occupancy number is high and gluons start to overlap.

Jerzy Łukasik has been an Associate Professor at the IFJ PAN since 2016. He obtained his PhD in 1993 from the Jagiellonian University. It concerned the properties of symmetric nuclear matter based on the predictions of his QMD code CHIMERA. He obtained the habilitation in 2015 from the IFJ PAN. It referred to the collective effects, the dynamics of heavy ion reactions at intermediate energies and their relation to the nuclear equation of state. He worked on various aspects of heavy ion collisions at IPN-Orsay (1995/96, INDRA), at GSI-Darmstadt (1998-2007, ALADIN) and also actively participated in the ASY-EOS and SPiRIT Collaborations performing experiments at GSI and at RIKEN. Since 2009 he has been a project leader of three grants and the main contractor of one project. All they resulted in construction of 3 detection systems: KRATTA, KATANA and KRAB. Currently he is a co-spokesperson of the ASY-EOS II Collaboration aiming at precise determination of the density dependence of the symmetry energy up to about twice the normal density. He has an experience in simulations of heavy ion collisions, data analysis, detector design and construction, simulations of experimental setups and detectors.

Maciej Trzebiński defended his PhD in 2013 at the Institute of Nuclear Physics, Polish Academy of Sciences and the Université Paris-Sud 11 with 1st class honors. Since then, he has been employed at the Institute of Nuclear Physics as an assistant professor. During that time he has spent 3 years at CERN, financed from the Mobility+ programme, serving as ATLAS Forward Proton (AFP) Technical Coordinator and AFP Run Coordinator. His research interests concentrate on various aspects of diffraction at HEP: starting from phenomenology (collaboration with Prof. A. Szczurek’s group from Krakow), through Monte Carlo generators (PI of project to develop GenEx-MC for exclusive light meson production) and detector operation, to analysis of data (PI of project “Studies of Hard Diffractive Production with the ATLAS Experiment”; 2020-2025). Finally, I am interested in outreach, being an official CERN guide, leader of few projects for high school and university students and organizer of the Particle Physics Summer Student Programme at the Institute of Nuclear Physics.

Adam Trzupek earned his PhD at Jagellonian University in theoretical physics in 1988. Next he was employed at the Institute of Nuclear Physics in Kraków, where he currently works as an associate professor in the ATLAS Experiment Department. His main area of interest is the physics of a new state of matter, the Quark-Gluon Plasma (QGP) created in ultra-relativistic heavy-ion collisions. He has been involved in relativistic heavy-ion experiments, in particular, he was actively engaged in the PHOBOS experiment at BNL and presently in the ATLAS experiment at CERN. To pursue these experimental tasks and to gain scientific experience, he has worked a total of almost 4 years in foreign laboratories at Oxford University, University of Notre Dame, Massachusetts Institute of Technology, Brookhaven National Lab and CERN. He has supervised two PhD thesis and has been a Principal Investigator on two Polish National Science Center projects.
