Dalitz-plot analysis of B+- --> K+-K+K- decays

TL;DR

This paper analyzes B+- --> K+-K+K- decays using QCD factorization, fitting model parameters to experimental data, and investigates CP violation and mass distributions across the Dalitz plot.

Contribution

It introduces a detailed QCD-based model including final state interactions to describe decay distributions and CP asymmetries in B+- --> K+-K+K- decays.

Findings

Model fits well to BABAR and LHCb data.

Describes K Kbar mass distributions accurately.

Examines CP-violating asymmetries across the Dalitz plot.

Abstract

We study B+- -- > K+-K+K- decays using the QCD factorization model with final state interactions between K+ and K- mesons taken into account. The parameters of the model are fitted to the data of the BABAR and LHCb collaborations. We describe the K Kbar effective mass distributions and examine the CP-violating asymmetry effects in the full range of the Dalitz plot.
