Spectroscopy of doubly charmed baryons:

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...

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 ...

Cabibbo favored hadronic decays of charmed baryons in flavor SU(3).

The two body Cabibbo favored hadronic decays of charmed baryons Λ+c , Ξ + c and Ξ 0 c into an octet or decuplet baryon and a pseudoscalar meson are examined in the SU(3) symmetry scheme. The numerical estimates for decay widths and branching ratios of some of the modes are obtained and are in good agreement with experiment. PACS number(s): 13.30.Eg, , 11.30.Hv, 11.40.Ha, 14.20.Kp

Charmed baryons in lattice QCD

Masses of singly and doubly charmed baryons are calculated in quenched lattice QCD using an improved action of the D234 type on an anisotropic lattice. The mass differences between spin 3/2 and spin 1/2 baryon states are calculated and compared to mass differences between vector and pseudoscalar mesons. The suppression of spin splittings in mesons containing heavy quarks, characteristic of quen...
