Pi pi scattering in three flavor ChPT : ππ scattering in three flavour ChPT

Bijnens, Johan LU orcid ; Dhonte, Pierre LU and Talavera, Pere (2004) In Journal of High Energy Physics 05(JHEP01(2004)).
Abstract
We present the scattering lengths for the pi-pi processes in the three flavour Chiral Perturbation Theory (ChPT) framework at next-to-next-to-leading order. We then combine this calculation with the determination of the parameters from $Ke4 and the masses and decay constants and compare with the results of a dispersive analysis of pi-pi scattering. The comparison indicates a small but nonzero value for the 1/Nc suppressed NLO low energy constants L4r and L6r.
