Abstract

A study of (D+KS0) and (DK+)-K-0 final states is performed in a sample of 1.0 fb(-1) of p p collision data collected at a centre-of-mass energy of root 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), Gamma(D*(s1) (2700)(+)) = 115.8 +/- 7.3(stat) +/- 12.1(syst) MeV = c(2), m(D*(s1) (2700)(+)) = 2866.1 +/- 1.0(stat) +/- 6.3(syst) MeV = c(2), Gamma(D*(s1) (2700)(+)) = 69.9 +/- 3.2(stat) +/- 6.6(syst) MeV = c(2).
