Heavy-Quark Symmetry and the Electromagnetic Decays of Excited Charmed Strange Mesons

Thomas Mehen, Roxanne P. Springer

Heavy-hadron chiral perturbation theory (HH$\chi$PT) is applied to the decays of the even-parity charmed strange mesons, D_{s0}(2317) and D_{s1}(2460). Heavy-quark spin symmetry predi…
