RELATIVISTIC MODEL OF HIDDEN BOTTOM TETRAQUARKS

Abstract

The relativistic model of the ground state and excited heavy tetraquarks with hidden bottom is formulated within the diquark–antidiquark picture. The diquark structure is taken into account by calculating the diquark–gluon vertex in terms of the diquark wave functions. Predictions for the masses of bottom counterparts to the charm tetraquark candidates are given.
