Phenomenology of the exclusive rare semileptonic decay B -> K pi l^+ l^-

TL;DR

This paper reviews the phenomenology of the exclusive B -> K pi l+ l- decay, focusing on the K* resonance and angular observables, and discusses constraints on Wilson coefficients from recent experimental data.

Contribution

It provides an updated review of angular observables and constraints on Wilson coefficients in B -> K pi l+ l- decays, emphasizing the K* resonance region.

Findings

Analysis of angular observables at dilepton mass spectrum ends

Constraints on Wilson coefficients C_7, C_9, C_10 from 2011 data

Reassessment of phenomenology with recent experimental results

Abstract

I review the phenomenology of exclusive Bbar -> Kbar pi l^+ l^- decays, with focus on the intermediate resonant Kbar^*(892) mode. The status of angular observables at both ends of the dilepton mass spectrum is revisited. Constraints on the b -> s Wilson coefficients C_7,C_9,C_10 based on 2011 data from the B factories, CDF and LHCb are presented.
