2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/40107I briefly review the current status of chiral perturbation theory in the meson sector. Emphasis is given on the quest for higher precision. I discuss two examples: one where it is difficult to make a good prediction (K_L -> pi^0 gamma gamma), and where CHPT, even when pushed to higher orders, cannot yield an increase in accuracy. The second one is pi pi scattering where a very sharp prediction can be made by combining CHPT at the two-loop level with dispersion relationsLatex 12 pages, Invited plenary talk at "Confinement IV", 4-8 July, ViennaHigh Energy Physics - Phenomenologytext
