TL;DR
This paper reports on a search for specific narrow resonances, including X(3872), in B+- to J/psi eta K+- decays using data from the Belle experiment, aiming to identify potential new states.
Contribution
First search for J/psi eta resonances, including X(3872), in B+- decays at Belle, expanding understanding of charmonium-like states.
Findings
No significant resonance signals observed.
Constraints set on resonance production rates.
Improved limits on X(3872) in this decay mode.
Abstract
We report study of B+- to J/psi eta K+- decays at Belle. In this analysis we search for X(3872) as well as other narrow resonances in the J/psi eta final state.
