40. Heavy Fermions and Flavor Physics beyond the SM

After a brief review of the status of the flavor physics phenomenology in the SM, I will focus on possible non-standard signals predicted by theories beyond the SM (especially Supersymmetry) in the flavor phenomenology of heavy fermions.

10. B mixing, supersymmetry and GUTs

Prof. Ulrich Nierste (Karlsruhe Institute of Technology (KIT))

The 2010 data on quark flavour physics reveal a considerable tension with the Standard Model. However, an excellent fit is found if one permits new physics in the amplitudes describing meson-antimeson mixing in the B_d and B_s systems. The corresponding global analysis disfavours the Standard Model at the level of 3.6 standard deviations and calls for new sources of CP violation in the...

32. SUSY_FLAVOR: a computational tool for FCNC and CP-violating processes in the MSSM

Janusz Rosiek (IFT UW)

I present SUSY_FLAVOR -- a library of programs that calculate important leptonic and semi-leptonic low-energy observables in the general R-parity conserving MSSM. Currently the code gives predictions for the K0-bar K0, D-bar D, B_d-bar B_d and B_s-bar B_s mixing parameters; B to X_s gamma, B_{s,d} to l+ l-, K0_L to pi nu-bar nu and K+ to pi+ nu-bar nu decay branching ratios; and the electric...

37. Complete resummation of chirally enhanced corrections in the general MSSM

Dr Andreas Crivellin (ITP Bern)

In the MSSM self-energies can be enhanced either by tan(beta) or by the trilinear A-terms and therefore lead to order one corrections. In this talk I show how these large corrections can be resummed to all order in perturbation theory. This resummation results in effective gluino, chargino, neutralino and Higgs boson vertices. Using these vertices all chirally enhanced effects can be...
