The Fock-Tani formalism is a first principle method to obtain effective interactions from microscopic Hamiltonians. The idea consists in a change of representation such that the operators associated with composite particles could be rewritten in operators who satisfy the canonical anticomutation relations. Starting from Fock space and using creation and annihilation operators to the constituents' particles, we consider a system contending quarks and antiquarks which could form bonded-states. In this new representation, the meson/baryon states can be constructed from meson/baryon creation operators. Originally derived for meson-meson or baryon-baryon scattering, we will present the corresponding equations for meson-baryon scattering.
