Constraining New Physics in B-->pi+pi- with Reparametrization Invariance and QCD Factorization
Patricia Ball, Aoife Bharucha
Usually, B->pi+pi- decays are expressed in terms of weak amplitudes explicitly dependent on the CKM weak phase alpha or gamma. In this letter, we show that the weak amplitudes can…

B --> K* mu+ mu-: SM and Beyond
Aoife Bharucha
The rare decay B --> K* mu+ mu- is considered to be a golden channel for LHCb, as the polarization of the K* allows a precise angular reconstruction resulting in many observables t…
