B->V gamma Beyond QCD Factorisation
Patricia Ball, Gareth W. Jones, Roman Zwicky
We calculate the main observables in and decays, i.e. branching ratios and CP and isospin asymmetries. We include QCD factorisation r…
Time-dependent CP Asymmetry in B->K* gamma as a (Quasi) Null Test of the Standard Model
Patricia Ball, Roman Zwicky
We calculate the dominant Standard Model contributions to the time-dependent CP asymmetry in B0->K*0 gamma, which is O(1/mb) in QCD factorisation. We find that, including all relev…
B -> K* gamma vs B -> rho gamma and |V_td/V_ts|
Patricia Ball, Roman Zwicky
We determine |V_{\rm td}/V_{\rm ts}| = 0.192 \pm 0.016_ exp \pm 0.014_th from B -> (K^*,rho) gamma as measured by the B-factories Babar and Belle. This version differs from the ori…
|V_td/V_ts| from B-> V gamma
Patricia Ball, Roman Zwicky
The dominant theoretical uncertainty in extracting |V_td/V_ts| from the ratio of branching ratios R=B(B->(rho,omega)gamma)/B(B->K* gamma) is given by the ratio of form factors xi=T…
