Abstract:
A study of $ {D^{+}}K_{\mathrm{S}}^0 $ 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 $ \sqrt{s}=7\;\mathrm{TeV} $ with the LHCb detector. We confirm the existence of the $ D_{s1}^{*}{{\left( {2700} \right)}^{+}} $ and $ D_{sJ}^{*}{{\left( {2860} \right)}^{+}} $ excited states and measure their masses and widths to be $ \begin{array}{*{20}{c}} {m\left( {D_{s1}^{*}{{{\left( {2700} \right)}}^{+}}} \right)=2709.2\pm 1.9\left( {\mathrm{stat}} \right)\pm 4.5\left( {\mathrm{syst}} \right)\mathrm{MeV}/{c^2},} \hfill \\ {\varGamma \left( {D_{s1}^{*}{{{\left( {2700} \right)}}^{+}}} \right)=115.8\pm 7.3\left( {\mathrm{stat}} \right)\pm 12.1\left( {\mathrm{syst}} \right)\mathrm{MeV}/{c^2},} \hfill \\ {m\left( {D_{sJ}^{*}{{{\left( {2860} \right)}}^{+}}} \right)=2866.1\pm 1.0\left( {\mathrm{stat}} \right)\pm 6.3\left( {\mathrm{syst}} \right)\mathrm{MeV}/{c^2},} \hfill \\ {\varGamma \left( {D_{sJ}^{*}{{{\left( {2860} \right)}}^{+}}} \right)=69.9\pm 3.2\left( {\mathrm{stat}} \right)\pm 6.6\left( {\mathrm{syst}} \right)\mathrm{MeV}/{c^2}} \hfill \\ \end{array} $
