The amount of the CP violation coming from the hadronic sector of the Standard model can be estimated by evaluating the precise shape of the CKM matrix elements. Recent experimental and theoretical progress requires a careful revision of the entries in that matrix. I will show why the errors on the value of the Cabbibo angle are underestimated and explain how one can improve them theoretically, show the new theory prediction and send the ball back to experimenters. Further improvement in the chiral behavior of the B^0-\bar B^0 mixing amplitude is also discussed.
15. 4. 2004	Dr. Jure Zupan	Izmeriti CKM kot gama iz B0 -> D KS.
8. 4. 2004	Dr. Rachel Jeannerot The Abdus Salam ICPT Trieste, Italy	Supersymmetric hybrid inflation. Supersymmetric hybrid inflation is one of the best motivated scenario from a particle physics point of view. It arises naturally in supersymmetric grand unified theories. In the standard scenario, spontaneous symmetry breaking occurs at the end of inflation and topological defects form. Therefore the GUT gauge group must break down to the standard model via at least one intermediate gauge symmetry to solve the monopole problem. All models compatible with observations lead to the formation of cosmic strings at the end of inflation. In order to solve the monopole problem in GUTs which break directly down to the standard model, one can use shifted hybrid inflation. The GUT symmetry is already broken during inflation, and no defect form at the end. Specific model based on the Pati-Salam gauge group will be discussed. The inflaton field at the end of inflation decays into right-handed (s)neutrinos reheating the universe and leptogenesis takes place. The model is consitent with experimental data on CMB, neutrinos oscillations and nucleosynthesis.
