Study of $D_{sJ}$ decays to $D^{+}\text{KS}$ and $D^0{K}^{+}$ final states in $pp$ collisions

A study of $D^{+}\text{KS}$ and $D^0{K}^{+}$ final states is performed in a sample of 1.0/fb of $pp$ collision data collected at a centre-of-mass energy of $\sqrt{s}=7$ TeV with the \lhcb detector. We confirm the existence of the $D_{s1}^{\ast }(2700{)}^{+}$ and $D_{sJ}^{\ast }(2860{)}^{+}$ excited states and measure their masses and widths to be {eqnarray} m(D_{s1}^(2700)^+) &=& 2709.2 \pm 1.9({stat})\pm,,,4.5({syst}) {MeV}/c^2,\cr \Gamma(D_{s1}^(2700)^+) &=& ,,,115.8 \pm 7.3({stat}) \pm12.1({syst}) {MeV}/c^2,\cr m(D_{sJ}^(2860)^+) &=& 2866.1 \pm 1.0({stat}) \pm,,,6.3({syst}) {MeV}/c^2,\cr \Gamma(D_{sJ}^(2860)^+) &=& ,,,,,,69.9 \pm 3.2({stat}) \pm,,,6.6({syst}) {MeV}/c^2.\cr {eqnarray}
