Riassunto:Title screen
A structure is observed in the B±K∓ mass spectrum in a sample of proton-proton collisions at centre-of-mass energies of 7, 8, and 13 TeV, collected with the LHCb detector and corresponding to a total integrated luminosity of 9fb−1. The structure is interpreted as the result of overlapping excited B0sBs0 states. With high significance, a two-peak hypothesis provides a better description of the data than a single resonance.
