Abstract
eceived 3 February 2006; published 12 June 2006 We report the first observation of Bs0→ψ(2S)ϕ decay in pp̅ collisions at √s=1.96   TeV using 360  pb-1 of data collected by the CDF II detector at the Fermilab Tevatron. We observe 20.2±5.0 and 12.3±4.1 Bs0→ψ(2S)ϕ candidates, in ψ(2S)→μ+μ- and ψ(2S)→J/ψπ+π- decay modes, respectively. We present a measurement of the relative branching fraction B(Bs0→ψ(2S)ϕ)/B(Bs0→J/ψϕ)=0.52±0.13(stat)±0.04(syst)±0.06(BR) using the ψ(2S)→μ+μ- decay mode.
