Strong decays of strange charmed P-wave mesons.
Goldstone boson decays of P-wave D s mesons are studied within the framework of Heavy Hadron Chiral Perturbation Theory. We first analyze the simplest single kaon decays of these strange charmed mesons. We derive a model independent prediction for the width of Ds2 and use experimental information on Ds1 to constrain the S-wave contribution to D 1 decay. Single and double pion decay modes are th...
متن کاملCharmed-strange Mesons Experimental Results
Two new states in the charm strange sector, D∗sJ(2317) + and DsJ(2460), have recently been discovered at e+e− collider experiments. The new states are first observed in the dominant Ds π0 and D∗+ s π0 modes respectively and are very narrow. They are consistent with 0+ and 1+ P-wave cs mesons. The DsJ(2460) meson is also observed in Ds γ and Ds π+π− modes. A review of the discoveries and possibl...
متن کاملProperties of the Charmed P-wave Mesons
Two broad charmed mesons, the D∗ 0 and D ′ 1, have recently been observed. We examine the quark model predictions for the D∗ 0 and D ′ 1 properties and discuss experimental measurements that can shed light on them. We find that these states are well described as the broad, j = 1/2 non-strange charmed P -wave mesons. Understanding the D∗ 0 and D ′ 1 states can provide important insights into the...
متن کاملS-wave charmed mesons in lattice NRQCD
Heavy-light mesons can be studied using the 1/M expansion of NRQCD, provided the heavy quark mass is sufficiently large. Calculations of the S-wave charmed meson masses from a classically and tadpole-improved action are presented. A comparison of O(1/M), O(1/M) and O(1/M) results allows convergence of the expansion to be discussed. It is shown that the form of discretized heavy quark propagatio...
متن کاملInclusive semileptonic decays of charm and charmed-strange mesons
We have measured the inclusive semileptonic branching fractions of D0, D+, and D+ s mesons. For these measurements, we have used the full CLEO-c open-charm data samples, 818 pb−1 at ECM = 3.774 GeV, giving D 0D̄0 and D+D− events, and 602 pb−1 at ECM = 4.170 GeV, giving D∗± s D ∓ s events. We obtain B(D0 → Xeνe) = (6.46± 0.09± 0.11)%, B(D+ → Xeνe) = (16.13± 0.10 ± 0.29)%, and B(D+ s → Xeνe) = (6....
