Abstract
We present an evaluation of the strong couplings and by an effective field theory of quarks and mesons. These couplings are necessary to calculate cross sections, an important background to the suppression signal in the quark-gluon plasma. We write down the general effective Lagrangian and compute the relevant couplings in the soft pion limit and beyond.
