27. On Bs to µµ within well-motivated theory frameworks, including the SM

Diego Guadagnoli (LAPTh Annecy)

The Bs to µµ decay is one of the milestones of the flavor program at the LHC. I will touch on certain aspects of the connection between the experimental and the theoretical observable. I will then discuss the impact of this observable on SM extensions, focusing on minimally model-dependent frameworks such as MFV or partial compositeness. It turns out that its constraining power is, depending...

29. Rare B decays at the NNLO in QCD

Mikolaj Krzysztof Misiak (University of Warsaw (PL))

16/04/2013, 14:52

Recent contributions to the evaluation of B -> Xs gamma and Bs -> mumu branching ratios at the next-to-next-to-leading order in QCD will be described. They include matching calculations at the electroweak scale as well as matrix element determination at the low energy scale.

36. Constraints on Wilson Coefficients from radiative B decays in a frequentist approach

Sébastien Descotes-Genon (LPT)

16/04/2013, 15:14

I discuss the constraints on the Wilson Coefficients of the effective Hamiltonian from B radiative decays within the frequentist approach developed by the CKMfitter group. A particular attention will be paid to the treatment of hadronic inputs and the sensitivity of observables (currently measured or planned to be) on this issue.

42. Hadronic effects in the exclusive b -> s transitions

The search for new physics in the flavour-changing neutral-current $b\to s \ell^+\ell^-$ transitions demands an accurate knowledge of the relevant hadronic parameters calculated in QCD. For the exclusive semileptonic $B$ decays, in addition to the form factors, also the relevant nonlocal hadronic matrix elements have to be estimated. I will discuss the hadronic effects in B\to K...

65. Isospin in B->K^(*)ll in and beyond the SM

Roman Zwicky (edinburgh university)

16/04/2013, 15:58

I will discuss the isospin asymmetry in and beyond the SM at low q2 (large recoil).

69. Flavour changing matrix elements for physics beyond the SM

Alessio Maiezza

Flavour changing neutral current and CP violating processes provide the testing ground for physics beyond the SM. The evaluation of the relevant hadronic matrix elements is crucial for the precision of the theoretical predictions. While waiting for precise lattice calculations we revisit the dipole and current-current K->pipi hadronic matrix elements in the framework of the phenomenological...
