Abstract

A study of D+ K0S and D0 K+ 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 = 7 TeV 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.
