Current research activities

Theoretical research is focused on the extended Standard Model (the Grimus-Neufeld model, where a second Higgs doublet and the fermionic neutrino singlet fields are added to the Standard Model fields) in collaboration with Th.Gajdosik group. Other theoretical research interests in particle physics include the supersymmetric SO(10) group, phenomenology of the neutrino sector, the multi Higgs-doublet model. Experimental particle physics research is carried out at the Compact muon solenoid (CMS) experiment at CERN. Proton-proton collision data is analyzed studying the Drell-Yan process. Participation in the muon system upgrade project GEM (gas electron multipliers) is focused on the development of the database systems (detector construction, online and offline) and their use in CMS software environment (CMSSW) in collaboration with the IT group from the Faculty of Mathematics and Informatics. A search for another suitable gas mixture for GEM detectors is being done as well. The members of the group participate in CMS “maintenance and operations” activities by taking shifts in the CMS control room and perform institutional reviews of the CMS publications.

Field of interest within the Center
