I review the implications of recent measurements of CP violation in D meson decays in the context of standard model extensions. Using effective theory methods, one can derive significant constraints on the possible non-standard contributions from measurements of neutral D meson mixing and direct CP violation in kaon decays. Explanations of the observed effect within several explicit well-motivated new physics frameworks are briefly discussed. Finally, possible future experimental tests able to distinguish standard vs. non-standard explanations of the observed CP violation in the charm sector are mentioned.

COBISS.SI-ID: 25831975I described the main theoretical difficulties in the description of proton decay and the way branching ratios can constrain different minimal unified theories. I particularly emphasized the SU(5) model with an extra fermionic adjoint and two supersymmetric versions of the renormalizable SO(10) model.
B.04 Guest lecture
COBISS.SI-ID: 26369319We published an article in the issue ''Modeli sveta'' of the journal Poligrafi on the topic of the Standard model and the problem of neutrino mass. In our paper, we presented the key concepts in the modern physics of elementary partices and sketched the conceptual and historical development of the Standard model. In the second part we discussed neutrino mass and the possibility of testing its origin at the Large Hadron Collider.
