Description
The focus on the talk is on tetraquarks – systems of two quarks and two antiquarks. In the meson-meson molecule picture and the impact of the quark exchange on the binding energy of the \chi_{c1}(3872). We introduce the quark exchange between two mesons in the in the T-matrix and solve the Bethe-Salpeter Equation for the different types of bound states, including X(6900) and estimate the impact of the Pauli blocking on the masses of the all-charm tetraquark resonances. We discuss the application of the indentical technique for a different types of tetraquarks.
