Recent developments in charm physics within the standard model and beyond are reviewed. The standard model contributions in the D0 - D0bar system are still under investigation including operators of higher dimensions. New physics models such as the Littlest Higgs model or warped extra-dimensional models might modify the amount of CP violation, although CP violating asymmetries are still predicted to be at most of the order 1%. The forward-backward asymmetry in the top anti-top pair production at the Tevatron is opening a new window in the study of new physics in the charm sector. New physics searches in rare charm decays are discussed. It is pointed out that in most models new physics effects in rare charm decays are insignificant.

COBISS.SI-ID: 2333284I started with general considerations on grand unification as a theory of proton decay and gave two explicit examples of predictive theories: the ordinary SU(5) and the supersymmetric SO(10) minimal cases. The talk was meant for experimentalists, and it was one of the two theoretical talks of the conference.

COBISS.SI-ID: 25461799Following recent intriguing experimental results on top quark pair production from the Tevatron I reviewed the present status of new physics explanations put forward to explain the experimental observations deviating from standard model predictions. All proposals face severe constraints from precise flavor, electroweak and other collider observables. Possible future measurements at the LHC able to discern among the various proposals are also discussed.
