We consider pion interactions in an effective field theory of the narrow resonance X(3872), assuming it is a weakly bound molecule of the charm mesons D0D̄*0 and D*0D̄0. Since the hyperfine splitting of the D0 and D*0 is only 7 MeV greater than the neutral pion mass, pions can be produced near threshold and are nonrelativistic. We show that pion exchange can be treated in perturbation theory and calculate the next-to-leading-order correction to the partial decay width Γ[X→D0D̄0π0]. © 2007 The American Physical Society.
