Krzysztof Poźniak is a Professor at the Institute of Electronic Systems within the Faculty of Electronics and Information Technology at Warsaw University of Technology. He holds a PhD and DSc (habilitation), specializing in experimental high energy physics with a focus on collider-based particle physics. His research is deeply integrated with the CMS Experiment at CERN's Large Hadron Collider (LHC), contributing to studies of Higgs boson properties, heavy ion collisions, and searches for beyond the Standard Model physics. University: Warsaw University of Technology Faculty: Faculty of Electronics and Information Technology Department: Institute of Electronic Systems Research interests include: Higgs boson self-coupling and production mechanisms Jet substructure and quark/gluon discrimination Heavy flavor physics in proton-proton and heavy ion collisions Detector development for high-luminosity LHC conditions Electroweak precision measurements Prominent recent work focuses on: Analysis of ttH production in b-bbar decay channels Studies of bottom quark energy loss in Pb-Pb collisions Searches for fractionally charged particles Measurement of WW and WZ cross sections at 13.6 TeV His group collaborates extensively with the CMS Collaboration, contributing to detector upgrades and data analysis frameworks. Over 740 documented publications reflect his leadership in experimental particle physics, with a particular emphasis on precision measurements and new physics searches.
