Charmed baryons in nuclear matter

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...

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...

Charmed matter

In the near future experiments will be able to produce charmed hadrons almost at rest in the interior of an atomic nucleus. One of the most exciting perspectives is the possibility of studying charmonium in a dense medium. In the present communication we present results of a study that explores the possibility that J/Ψmight be bound in a large nucleus through the excitation of intermediate stat...
