2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/39901I discuss the estimate of the CP-violating parameter eps'/eps based on hadronic matrix elements computed in the chiral quark model. This estimate suggested, before the current experimental results, that the favored value of eps'/eps in the standard model is of the order of 10^{-3}. I briefly review the physical effects on which this result is based and summarize current estimates.3 pages, LaTeX, conference proceedings, ICHEP2000, Osaka (July 27 - August 2, 2000), and IVth Rencontres du Vietnam, Hanoi (July 19-25, 2000)High Energy Physics - Phenomenologytext
