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...
