Abstract

We present the results of a lattice calculation of tetraquark states with quark contents q1q2¯Q¯Q,q1,q2⊂u,d,s,c and Q≡b, c in both spin-0 (J=0) and spin-1 (J=1) sectors. This calculation is performed on three dynamical Nf=2+1+1 highly improved staggered quark ensembles at lattice spacings of about 0.12, 0.09, and 0.06 fm. We use the overlap action for light to charm quarks, while a ...
