TL;DR

This paper analyzes B meson decays into D(*) and three pions using BaBar data, focusing on reconstructing specific decay modes and identifying the dominant decay channel.

Contribution

It presents a detailed study of B decays into D(*) and three pions, including reconstruction of exclusive and non-resonant modes, highlighting the dominant B->D(*)a_{1}(1260) decay.

Findings

Identification of the dominant B->D(*)a_{1}(1260) decay mode.

Reconstruction of B->D(*)a_{1}(1260), B->D(*)rho^{0} pi, and B->D(*)pipipi decays.

Analysis based on 57.4 fb^{-1} of data at the Upsilon(4S) resonance.

Abstract

Based on a data sample of an integrated luminosity of 57.4 fb-1 at the Upsilon(4S) resonance taken with the BaBar detector using the SLAC PEP-II asymmetric-energy $B$-Factory, hadronic decays of B meson with the final states D(*) and three pions are studied. The study is performed by fully reconstructing the exclusive decays of B->D(*)a_{1}(1260) and the non-resonant modes B->D(*)rho^{0} pi and B->D(*)pipipi. The current status of the study is presented and a dominant B->D(*)a_{1}(1260) decay is shown.
