Search for wrong flavour contribution to Bs → Ds + π

Matt Williams (Warwick University)


The decay of Bs → Ds has long been assumed to be flavour-specific, that is the contribution from Bs → Ds+ + π- is negligible or zero. The Standard Model predicts only a tiny contribution. To date, this assumption has never been explicitly tested despite the fact that many precision measurement at LHCb and elsewhere are based upon it. An analysis of the decay using the 2011 data from LHCb is presented.
