Abstract: A search is performed for DsJ(*) + mesons in the reactions pp → D∗ +KS0X and pp → D*0K+X using data collected at centre-of-mass energies of 7 and 8 TeV with the LHCb detector. For the D∗ +KS0 final state, the decays D*+ → D0π+ with D0 → K−π+ and D0 → K−π+π+π− are used. For D*0K+, the decay D*0 → D0π0 with D0 → K−π+ is used. A prominent Ds1(2536)+ signal is observed in both D∗ +KS0 and D*0K+ final states. The resonances Ds1*(2700)+ and Ds3*(2860)+ are also observed, yielding information on their properties, including spin-parity assignments. The decay Ds2*(2573)+ → D∗ +KS0 is observed for the first time, at a significance of 6.9 σ, and its branching fraction relative to the Ds2*(2573)+ → D+KS0 decay mode is measured.[Figure not available: see fulltext.]
