2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/192023I review basic concepts of chiral effective field theories guided by an historical perspective: from the first ideas to the merging with other effective frameworks, and to the interplay with lattice field theory. The impact of recent theoretical developments on phenomenological predictions is reviewed with attention for rare decays, and charm physics. I conclude with a critical look at future applications.13 pages, 2 figures, Invited Review at HADRON07, Frascati, October 8-13, 2007High Energy Physics - Phenomenologytext
