Open 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 ...
متن کاملHadronic scattering of charmed mesons
The scattering cross sections of charm mesons with hadrons such as the pion, rho meson, and nucleon are studied in an effective Lagrangian. In heavy ion collisions, rescattering of produced charm mesons by hadrons affects the invariant mass spectra of both charm meson pairs and dileptons resulting from their decays. These effects are estimated for heavy ion collisions at Super Proton Synchrotro...
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 کاملProduction of excited charmed mesons at LEP
Studies of the production of orbitally excited charmed and charmed strange mesons in eecollisions, performed by the LEP collaborations are reviewed. Measurements of the production rates of orbitally excited charmed mesons in semileptonic b decays are presented. Searches for charmed meson radial excitations are also briefly discussed.
متن کاملSemileptonic B decays to excited charmed mesons
Exclusive semileptonic B decays into excited charmed mesons are investigated at order ΛQCD/mQ in the heavy quark effective theory. Differential decay rates for each helicity state of the four lightest excited D mesons (D1, D ∗ 2, D∗ 0, andD ∗ 1) are examined. At zero recoil, ΛQCD/mQ corrections to the matrix elements of the weak currents can be written in terms of the leading IsgurWise function...
