List of questions:

  • SM calculation of BR(Bs-->
mumu): Summarize hte SM calculation with the different approaches. Is there a preferred calculation and where is it published?
ex1
A. Buras et al, arXiv:1007.5291: BR=(3.2+-0.2) x 10-9 and ex2: M. Bona et al. (UTFit Coll): BR= (3.7+-0.5)x10-9 Phys.Lett.B687 (2010) 61. at least in 1), the SM value is not calculated

  • What does the excess in B->tau nu tell us about BR Bsmumu and other rare decays?

  • In which model/scenario we might have a LFV decay of tau->mu gamma or tau--> 3 mu with a BR in the 10-9-10-10 range now that MEG put an upper limit on mu->e gamma at 2.4x10-12 ?

Session on LFV and rare D and B decays

This twiki page documents the discussion of LFV and rare B and D decays for the LHCb-Theory workshop in November 2011.

Session organisation

A preliminary agenda for the session is:

Talk Description Speaker
Introduction (5 min) Brief introduction of the session  
Interplay between direct and indirect searches (30 min ) Summary of interplay between direct and indirect search results, including results from global fits  
Constraints on Wilson coefficients from global fits (20 min) Overview of the constraints on C7, C9, C10 coming from global fits of radiative Bd decays and Bd -> K* mu mu. What measurements can we include to improve sensitivity to NP.  
LHCb summary: Prospects for Bd -> K* mu mu, Bd -> K* gamma and related channels (20 min) Overview of LHCb prospects for Winter conferences and 2012  
Observables in b -> s (d) mu mu and b -> s (d) gamma decays (20 min) What new observables can we add? What do large Isospin asymmetries tell us about NP? CP violation in rare decays?  
Coffee and discussion (30 min)  
LHCb summary: reach in rare decay searches (20 min) Summary of LHCb's sensitivity in rare decay searches for Winter conferences and 2012  
Searches with non-LFV channels (30 min) Prospects for D0 -> mu mu, Bs(d) -> mu mu (and tau tau). Correlations between rare decay searches and mixing in B and Charm  
LFV searches (30 min) Review of LFV tau decays after MEG. What are the correlations between charged and photon modes? What are the correlations between LFV tau decays and searches for non-LFV B and D decays.
