#### **Roman Pasechnik**

Roman Pasechnik, born 1983, is an associate professor at the Department of Astronomy and Theoretical Physics at Lund University in Lund. His research is focused on theoretical studies of strongly interacting field theories and their implications in collider physics and in the early universe as well as on New Physics model building and its applications in collider phenomenology and astroparticle physics. He obtained his PhD at JINR, Dubna, for studies of non-perturbative aspects of QCD.

#### **Michal Sumbera ˇ**

Michal Sumbera, born 1951, is a senior physicist at the NPI CAS and lecturer at the Czech ˇ Technical University in Prague. His scientific work focuses mainly on ultrarelativistic heavy ion collisions at the LHC and RHIC (experiments ALICE and STAR) and on high-energy phenomenology. In the past, he was involved in CERN SPS experiments NA45 and WA98 and also in TAPS experiment at GSI. He obtained his PhD at JINR, Dubna, for studies of light nuclei interactions from Synchrophasotron with photoemulsion nuclei
