Study of D sJ decays to {D+}KS^0 and D 0K+ final states in pp collisions
Abstract
A study of {D+}KS^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 √{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},} {\varGamma ( {D_{s1}^{*}{{{( {2700} )}}+}} )=115.8± 7.3( {stat} )± 12.1( {syst} )MeV/{c^2},} {m( {D_{sJ}^{*}{{{( {2860} )}}+}} )=2866.1± 1.0( {stat} )± 6.3( {syst} )MeV/{c^2},} {\varGamma ( {D_{sJ}^{*}{{{( {2860} )}}+}} )=69.9± 3.2( {stat} )± 6.6( {syst} )MeV/{c^2}}.
