We try to obtain such constraints by statistical methods from the decay width of the \u03B7RIGHTWARDS ARROW\u03C0+\u03C0MINUS SIGN \u03C00 decay in the framework of resummed chiral perturbation theory. We rely on recent estimates of the isospin violating parameter R, which is proportional to the difference of the u and d quark masses.
