How to Search for Doubly Charmed Baryons and Tetraquarks
Moinester, Murray A.
Original · EN
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: Ξcc⁺ (ccd), Ξcc⁺⁺ (ccu), and Ωcc⁺ (ccs); and the tetraquark is T (ccud). Estimates are given of masses, lifetimes, internal structure, production cross sections, decay modes, branching ratios, and yields. Experimental requirements are given for optimizing the signal and minimizing the backgrounds. The discussion is in the spirit of an experimental and theoretical review, as part of the planning for a CHarm Experiment with Omni-Purpose Setup (CHEOPS) at CERN. The CHEOPS objective is to achieve a state-of-the-art very charming experiment, in the spirit of the aims of the recent CHARM2000 workshop.
