DOUBLY CHARMED MESONS

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 ...

Hadronic 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...

Charmed-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...

Doubly Charmed Baryons in Compass

The search for doubly charmed baryons has been a topic for COMPASS from the beginning. Requiring however a complete spectrometer and highest possible trigger rates this measurement has been postponed. The scenario for such a measurement in the second phase of COMPASS is outlined here. First studies of triggering and simulation of the setup have been performed. New rate estimates based on recent...
