Title: First Observation of B s 0→J/ψη and B s 0→J/ψη'

Abstract

We report first observations of B s 0→J/ψη and B s 0→J/ψη'. The results are obtained from 121.4 fb⁻¹ of data collected at the Υ(5S) resonance with the Belle detector at the KEKB e⁺e⁻ collider. We obtain the branching fractions B(B s 0→J/ψη)=[5.10±0.50(stat)±0.25(syst) +1.14 -0.79(NB(*)sB¯¯¯(*)s)]×10⁻⁴, and B(B s 0→J/ψη')=[3.71±0.61(stat)±0.18(syst) +0.83 -0.57(N B(*)sB¯¯¯(*)s)]×10⁻⁴. The ratio of the two branching fractions is measured to be (B(B s→J/ψη'))/(B(B s→J/ψη))=0.73±0.14(stat)±0.02(syst).
