Abstract

A search is performed for D(*)+sJ mesons in the reactions pp → D∗+ K0S X and pp → D*0 K+ X using data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb detector. For the D∗+ K0S final state, the decays D*+ → D0 π+ with D0 → K− π+ and D0 → K− π+ π+ π− are used. For D*0 K+, the decay D*0 → D0 π0 with D0 → K− π+ is used. A prominent D*s1(2536)+ signal is observed in both D∗+ K0S and D*0 K+ final states. The resonances D*s1(2700)+ and D*s3(2860)+ are also observed, yielding information on their properties, including spin-parity assignments. The decay D*s2(2573)+ → D∗+ K0S is observed for the first time, at a significance of 6.9 σ, and its branching fraction relative to the D*s2(2573)+ → D+ K0S decay mode is measured.
