Doubly charmed tetraquarks in a diquark–antidiquark model.

We study the spectra of the doubly charmed tetraquark states in a diquark–antidiquark model. The doubly charmed tetraquark states form an antitriplet and sextet configurations according to flavor SU(3) symmetry. For the tetraquark state [qq′][c̄c̄], we show the mass for both bound and excited states. The two-body decays of tetraquark states Tcc[0+] and Tcc[1−−] to charmed mesons have also been studied. In the end, the doubly charmed tetraquarks decays to a charmed baryon and a light baryon have been studied in the SU(3) flavor symmetry. [ABSTRACT FROM AUTHOR]
