Properties 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 کاملStrong 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 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 کاملHadronic production of S-wave and P-wave charmed b mesons via heavy quark fragmentation.
At hadron colliders the dominant production mechanism of (b̄c) mesons with large transverse momentum is due to parton fragmentation. We compute the rates and transverse momentum spectra for production of S-wave and P-wave (b̄c) mesons at the Tevatron via the direct fragmentation of the bottom antiquark as well as the AltarelliParisi induced gluon fragmentation. Since all the radially and orbitall...
متن کاملOpen Flavor Charmed Mesons
We present here recent results on the investigations of the mass spectrum ( S-states and P-states), decay constants, decay widths and life time of the D, Ds,and Bcmesons within the framework of phenomenological potential models.We also present the binding energy and the masses of the di-meson molecular systems with one or more charm meson combinations. Many of the newly found experimental open ...
