Observation of Bs → ψ(2S)φ and
Measurement of Br(Bs → ψ(2S)φ)/Br(Bs → J/ψφ)

This page summarizes the results for Observation of Bs → ψ(2S)φ in both di-muon and J/psi pipi mode and the measurement of the relative branching ratio between Bs → ψ(2S)φ and Bs → J/ψ φ using only di-muon mode.

There is a complete version of the results: html, ps.


Results

1. First observation of Bs → ψ(2S)φ with 6.35 &sigma significance using both di-muon mode and J/&psi &pi π mode
2. Measurement of Br(Bs → ψ(2S)φ)/Br(Bs → J/ψφ) = 0.52 ± 0.13[stat.] ± 0.04[syst.] ± 0.06[BR] using di-muon mode
