Measurement of branching ratio and B[subscript s][superscript 0] lifetime in the decay B[subscript s][superscript 0]→J/ψf0(980) at CDF
We present a study of B[subscript s][superscript 0] decays to the CP-odd final state J/ψf[subscript 0](980) with J/ψ→μ+μ- and f0(980)→π[superscript +]π[superscript -].

| description | We present a study of B[subscript s][superscript 0] decays to the CP-odd final state J/ψf[subscript 0](980) with J/ψ→μ+μ- and f0(980)→π[superscript +]π[superscript -]. Using pp̅ collision data with an integrated luminosity of 3.8 fb[superscript -1] collected by the CDF II detector at the Tevatron we measure a B[subscript s][superscript 0] lifetime of τ(B[subscript s][superscript 0]→J/ψf[subscript 0](980))=1.70[subscript -0.11][superscript +0.12](stat)±0.03(syst)ps. This is the first measurement of the B[subscript s][superscript 0] lifetime in a decay to a CP eigenstate and corresponds in the standard model to the lifetime of the heavy B[subscript s][superscript 0] eigenstate. We also measure the product of branching fractions of B[subscript s][superscript 0]→J/ψf[subscript 0](980) and f0(980)→π[superscript +]π[superscript -] relative to the product of branching fractions of B[subscript s][superscript 0]→J/ψϕ and ϕ→K[superscript +]K[superscript -] to be R[subscript f0/ϕ]=0.257±0.020(stat)±0.014(syst), which is the most precise determination of this quantity to date. |
