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

A study of $D^+\\KS$ and $D^0K^+$ 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 $D_{s1}^*(2700)^+$ and $D_{sJ}^*(2860)^+$ 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}
