Exploring New Physics in C_7-C_7'

Descotes-Genon, S., Ghosh, D., Matias, J. et al.

Understand

We discuss the model dependence in the determination of the Wilson coefficient C_7 that governs the radiative electromagnetic decays of B mesons in the Standard Model, by considering various extensions of the effective Hamiltonian used to describe such decays.

We include already measured observables like the branching ratios of B->X_s mu+ mu- and B->X_s gamma, the isospin and CP asymmetries in B->K* gamma, as well as A_FB and F_L in B->K* l+ l-, adding the LHCb measurements presented at this conference.
We explore the constraints on C_7,C_9,C_10 as well as their chirality-flipped counterparts.
We also discuss the transverse asymmetry A_T^2 which, once measured, may help to disentangle some of the scenarios considered.
