Search for the State Decaying into in Proton-Proton Collisions at
Here, a search for resonancelike structures in the B0sπ± invariant mass spectrum is performed using proton-proton collision data collected by the CMS experiment at the LHC at √s = 8 TeV, corresponding to an integrated luminosity of 19.7 fb–1. The B0s mesons are reconstructed in the decay chain B0s → J/ψΦ, with J/ψ → μ+μ– and Φ → K+K–. The B0sπ± invariant mass distribution shows no statistically significant peaks for different selection requirements on the reconstructed B0s and π± candidates. Upper limits are set on the relative production rates of the X(5568) and B0s states times the branching fraction of the decay X(5568)± → B0sπ±. In addition, upper limits are obtained as a function of the mass and the natural width of possible exotic states decaying into B0sπ±.
