英文摘要	The light cone QCD sum rules are derived for the KK pi coupling gKK pi and the rho pi pi coupling g rho pi pi. The contribution from the excited states and the continuum is subtracted cleanly through the double Borel transform with respect to the two external momenta, p(1)(2) p(2)(2) = (p-q)(2). Our result gK*K pi = (8.7 +/- 0.5) and g(rho pi pi) = (11.5 +/- 0.8) is in good agreement with the experimental value.
