Low energy constants from K(l4) form-factors
(2000) In Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics 480(1-2). p.71-76- Abstract
We have calculated the form-factors F and G in K → ππlν decays (K(l4)) to two-loop order in Chiral Perturbation Theory (ChPT). Combining this together with earlier two-loop calculations an updated set of values for the L(i)/(r), the ChPT constants at O(p4), is obtained. We discuss the uncertainties in the determination and the changes compared to previous estimates. (C) 2000 Elsevier Science B.V.
