Search for the X (5568) state decaying into Bs0 π± in proton-proton collisions at s =8 TeV
A search for resonancelike structures in the B0 sπ invariant mass spectrum is performed using protonproton collision data collected by the CMS experiment at the LHC at ffiffi s p ¼ 8 TeV, corresponding to an integrated luminosity of 19.7 fb−1. The B0 s mesons are reconstructed in the decay chai...

| description | A search for resonancelike structures in the B0
sπ invariant mass spectrum is performed using protonproton
collision data collected by the CMS experiment at the LHC at ffiffi
s p ¼ 8 TeV, corresponding to an
integrated luminosity of 19.7 fb−1. The B0
s mesons are reconstructed in the decay chain B0
s → J=ψϕ, with
J=ψ → μþμ− and ϕ → KþK−. The B0
sπ invariant mass distribution shows no statistically significant
peaks for different selection requirements on the reconstructed B0
s and π candidates. Upper limits are set
on the relative production rates of the Xð5568Þ and B0
s states times the branching fraction of the decay
Xð5568Þ → B0
sπ. In addition, upper limits are obtained as a function of the mass and the natural width of
possible exotic states decaying into B0
sπ. |
