Exploring New Physics in the C7-C7' plane
Sebastien Descotes-Genon, Diptimoy Ghosh, Joaquim Matias +1
The Wilson coefficient C7 governing the radiative electromagnetic decays of B meson has been calculated to a very high accuracy in the Standard Model, but experimental bounds on ei…
Complete Anatomy of B -> K*ll and its angular distribution
Joaquim Matias, Federico Mescia, Marc Ramon +1
We present a complete and optimal set of observables for the exclusive 4-body B meson decay B -> K*(->K pi) l+l- in the low dilepton mass region, that contains a maximal number of…
New physics reach of the decay mode
Ulrik Egede, Tobias Hurth, Joaquim Matias +2
We present a complete method to construct QCD-protected observables based on the exclusive 4-body -meson decay in the low dilepton mass re…
Symmetries in the angular distribution of exclusive semileptonic B decays
Ulrik Egede, Tobias Hurth, Joaquim Matias +2
We discuss a method to construct observables protected against QCD uncertainties based on the angular distribution of the exclusive Bd -> K(*0}(-> Kpi) l+ l- decay. We focus on the…
Implications from clean observables for the binned analysis of B -> K*ll at large recoil
Sebastien Descotes-Genon, Joaquim Matias, Marc Ramon +1
We perform a frequentist analysis of q^2-dependent B-> K*(->Kpi)ll angular observables at large recoil, aiming at bridging the gap between current theoretical analyses and the actu…
