Probing unknown nonperturbative effects in $b \to s ℓℓ$ with inclusive and exclusive observables

P. Alvarez-Cartelle, B. Capdevila, E. Lunghi +1

In this paper we revisit, from a different perspective, a long-standing question: ``Is the systematic deficit observed in all branching ratios mediated by a $b \to s I^¼ I^¼$ transitio…

Structure functions for the inclusive semileptonic $b$ -quark decay at NNLO: a semi-analytic calculation

A. Broggio, B. Capdevila, A. Ferroglia +1

We present a study of the inclusive charmless semileptonic $b$ decay, $b \to X_{u} ℓ I^ˉ ½$ at next-to-next-to-leading order (NNLO) in perturbative QCD, with the primary aim of extr…

Model-independent unbinned analysis of $B \to K^{*} (\to K^{+} I ¨ ^{-}) I^¼^{+} I^¼^{-}$ : zeroes, bounds, Wilson coefficients and symmetries

Bernat Capdevila, Joaquim Matias, MartÃn Novoa-Brunet +2

We present a model-independent method to study the four-body decay $B \to K^{*} (\to K^{+} I ¨ ^{-}) I^¼^{+} I^¼^{-}$ , based on extracting continuous observables with a moments approach. The method a…
