Research Topics
|
Theoretical Particle Physics:
- Unified theories of quarks and leptons, grand unification and superunification,
superstring phenomenology;
- Quark-lepton families and flavor physics, flavor-changing rare processes;
- Local and global conservation laws, nature of gauge invariance, emergent gauge
and gravity theories;
- Spontaneous violation of relativistic invariance at the small distances and its
physical and astrophysical consequences;
- Extra space-time dimensions, elaboration of the brane models with large and
infinite extra space-time dimensions.

|
Cosmic Ray Physics:
- Investigation of the primary content of high energy cosmic rays in Extensive Air
Showers studying both muon and hadron component spectra;
- Data analysis related to super-high energy cosmic particles to find a possible
deviation from a strict Special Relativity (like as the Greizen-Zatsepin-Kouzmin
cutoff breaking and other phenomena);
- Scientific-Educational Project in Cosmic Ray Physics: Investigation of Extensive
Air Showers by constructing of the Network of the Cosmic Rays Stations in
Georgia allocated in high schools and universities. Currently three CR stations operate.

Particle Physics on Accelerators:
Experimental research on accelerators is virtually dominated by the DEPP participation
in the ALICE, ATLAS and CMS experiments at LHC (CERN) and the corresponding data analysis.
