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...

How to Search for Doubly Charmed Baryons and Tetraquarks

Possible experimental searches of doubly charmed baryons and tetraquarks at fixed target experiments with high energy hadron beams and a high intensity spectrometer are considered here. The baryons considered are: Ξ+cc (ccd), Ξ cc (ccu), and Ω + cc (ccs); and the tetraquark is T (ccūd̄). Estimates are given of masses, lifetimes, internal structure, production cross sections, decay modes, branchi...
