X(3872) rediscovery from B decay with 62.8 fb-1 of Phase 3 data at Belle II

The Belle II Collaboration

12 March 2021

Abstract: The decay of B -> J/psi pi+ pi- K is studied using 62.8 fb-1 data collected at the Upsilon(4S) resonance. Evidence for B -> X(3872) K with a statistical significance of 4.6sigma is found. This note contains the public plots associated with the internal note BELLE2-NOTE-PH-2020-025.

The record appears in these collections:
Belle II Notes (Public) > Belle II Notes : Approved plots
