“…Their preliminary result did not yield a signal and they extract an upper limit on the branching fraction of B(B 0 s → J/ψf 0 )B(f 0 → π + π − ) < 1.63 × 10 −4 at 90% C.L. Recently the LHCb experiment reported the first observation of the decay B 0 s → J/ψf 0 [21] with a relative branching fraction of R f0/φ = 0.252 +0.046 −0.032 (stat) +0.027 −0.033 (syst). Shortly after the LHCb result was presented, the Belle collaboration announced their result of an updated analysis using 121.4 fb −1 of Υ(5S) data [22].…”

The effective lifetime of the " B 0 s meson in the decay mode " B 0 s ! J=c f 0 ð980Þ is measured using 1:0 fb À1 of data collected in pp collisions at ffiffi ffi s p ¼ 7 TeV with the LHCb detector. The result is 1:700 AE 0:040 AE 0:026 ps, where the first uncertainty is statistical and the second systematic. As the final state is CP-odd, and CP violation in this mode is measured to be small, the lifetime measurement can be translated into a measurement of the decay width of the heavy " B 0 s mass eigenstate, À H ¼ 0:588 AE 0:014 AE 0:009 ps À1 .

The branching fractions of the semileptonic and rare B s decays are calculated in the framework of the QCD-motivated relativistic quark model. The form factors of the weak B s transitions are expressed through the overlap integrals of the initial and final meson wave functions in the whole accessible kinematical range. The momentum transfer dependence of the form factors is explicitly determined without additional model assumptions and extrapolations. The obtained results agree well with available experimental data.
