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

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

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

A complete description of P- and S-wave contributions to the $B^{0} \to K^{+} π^{-} ℓ^{+} ℓ^{-}$ decay

Marcel Algueró, Paula Alvarez Cartelle, Alexander Mclean Marshall +6

In this paper we present a detailed study of the four-body decay $B^{0} \to K^{+} π^{-} ℓ^{+} ℓ^{-}$ , where tensions with the Standard Model predictions have been observed. Our ana…

First branching fraction measurement of the suppressed decay $Ξ_{c}^{0} \to π^{-} Λ_{c}^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The $Ξ_{c}^{0}$ baryon is unstable and usually decays into charmless final states by the $c \to s u d$ transition. It can, however, also disintegrate into a $π^{-}$ meson and a…
