Hadrons, composed of quarks and gluons bound by Quantum Chromodynamics (QCD), traditionally classified as baryons (three quarks) and mesons (quark-antiquark pairs). Nothing in the theory of QCD stands against the existence of exotic hadrons with more complex quark contents. Recent discoveries by LHCb and Belle, such as X, Y, Z states and Tcc(3875), have renewed interest in these states. Understanding the binding mechanism within of these exotic states provides insights into QCD's non-perturbative dynamics. This work presents lattice QCD studies of two-meson interactions, involving bottom quarks, on MILC ensembles, exploring heavy tetraquark channels.
