Resumen

Abstract: A search is performed for D sJ (*) + mesons in the reactions pp → D ∗ +K S 0X 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 ∗ +K S 0 final state, the decays D *+ → D 0π + with D 0 → K π + and D 0 → K π +π +π are used. For D *0K +, the decay D *0 → D 0π 0 with D 0 → K π + is used. A prominent D s1(2536) + signal is observed in both D ∗ +K S 0 and D *0K + 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 ∗ +K S 0 is observed for the first time, at a significance of 6.9 σ, and its branching fraction relative to the D s2 *(2573) + → D +K S 0 decay mode is measured.[Figure not available: see fulltext.]
