Abstract

In this paper, Tetraquark is considered as a bound state of 4-quark systems containing two
heavy-heavy antiquarks and two light-light quarks ss. Tetraquark is also assumed as a 2-body
system consisting of two mesons; each containing a light quark and a heavy quark. BornOppenheimer approximation could be employed due to the mesons’ heavy weight. Hence, the
Schrödinger equation may be solved by replacing the ensuing potential from lattice QCD. Having
solved the equations, the binding energy and tetraquark wave function are then obtained in scalar
ss channel. Finally, obtained values for binding energy are compared with those reported in the
literature, and considering the wave function diagrams for the particle, its tetraquark radius is
estimated.
