The doubly charmed pseudoscalar tetraquarks Tcc;s¯s¯++ and Tcc;d¯s¯++
The mass and coupling of the doubly charmed JP=0− diquark–antidiquark states Tcc;s¯s¯++ and Tcc;d¯s¯++ that bear two units of the electric charge are calculated by means of QCD two-point sum rule method. Computations are carried out by taking into account vacuum condensates up to and including terms...
