We review the main constraints on the parameter space of the minimal renormalizable supersymmetric SU(5) grand unified theory. They consist of the Higgs mass, proton decay, electroweak symmetry breaking and fermion masses. Superpartner masses are constrained both from below and from above, giving hope for confirming or definitely ruling out the theory in the future.

COBISS.SI-ID: 27317287Rigorous treatment of near-threshold bound states and resonances still presents a challenge for lattice simulations. A possible way to treat them is to simulate the corresponding scattering on the lattice. As an example, I presented results for the charmonium(like) state X(3872) and the scalar meson Ds0(2317), which are shallow bound states in the DD* and DK channels, respectively. I also discussed strange, charmed and charmonium resonances.

COBISS.SI-ID: 2611556I presented how masses and widths of hadron resonances are extracted from lattice QCD. Recent lattice results on light, strange and charm meson resonances were reviewed. Their properties are extracted by simulating the corresponding scattering channels and extracting the scattering phase shifts.

COBISS.SI-ID: 2602084Recent disagreement between experimental measurments of CP violating asymmetry in D0-) K+ K- and D0 -) pi+ pi- and theoretical Standard model expectation motivated many studies within the Standard model and beyond. Rare charm decays offer new probe of possible signals beyond Standard model. CP conserving and CP violating contributions within the Standard model and beyond are reviewed for inclusive c -) u gamma in c -)u l+ l- and exclusive D -) V gamma, D -) P+ P- gamma, D+-)pi+ l+ l- and D0-) l+ l- decays.
