Abstract: | A study of D+K0S and D 0 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√=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/c2,Γ(D∗s1(2700)+)=115.8±7.3(stat)±12.1(syst)MeV/c2,m(D∗sJ(2860)+)=2866.1±1.0(stat)±6.3(syst)MeV/c2,Γ(D∗sJ(2860)+)=69.9±3.2(stat)±6.6(syst)MeV/c2 $ |
