Abstract

A study of D +K S 0 and D 0K + final states is performed in a sample of 1.0 fb -1 of pp collision data collected at a centre-of-mass energy of √s = 7TeV with the LHCb detector. We confirm the existence of the D s1 *(2700) + and D sJ * (2860) + excited states and measure their masses and widths to be m(D s1 * (2700) +) = 2709:2 ± 1:9(stat) ± 4:5(syst) MeV/c 2;Γ(D s1 *(2700) +) = 115:8 ± 7:3(stat) ± 12:1(syst) MeV/c 2; m(D sJ *(2860) +) = 2866:1 ± 1:0(stat) ± 6:3(syst) MeV/c 2; Γ(D sJ *(2860) +) = 69:9 ± 3:2(stat) ± 6:6(syst) MeV/c 2.
