A.Garmash, et al. (for the Belle Collaboration)
TL;DR
This paper presents a Dalitz plot analysis of the three-body charmless decay B0=>K0pi+pi-, measuring branching fractions for various quasi-two-body decay modes using a large data sample from the Belle experiment.
Contribution
It provides the first detailed Dalitz analysis of this decay mode and reports new measurements of branching fractions and upper limits for several decay channels.
Findings
Measured branching fractions for B0=>rho(770)0K0 and other modes.
Set upper limits on several decay channels.
Analyzed decay dynamics with a large data sample.
Abstract
We report results of a Dalitz plot analysis of the three-body charmless B0=>K0pi+pi- decay. The analysis is performed with a data sample that contains 388 million BBbar pairs collected near the Y(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. Measurements of branching fractions for the quasi-two-body decays B0=>rho(770)0K0, B0=>f0(980)K0, B0=>K*(892)+pi-, B0=>K*(1430)+pi-, and upper limits on several other quasi-two-body decay modes are reported.
