We study the time dependence of the integrated asymmetries in strangeness of kaons in the decays in two and three pions and in two photons with the purpose of disentangling the CP violating effects in the decay amplitudes from the ones related to the K0-K0BAR mass matrix. We find two cases where they are not reduced by the DELTA-I=1/2 rule or hidden by CP violation in the mass matrix, namely the strangeness-energy correlation of the charged pions in the prompt decay (tau < tau(s)) in pi+ pi--pi-0, and the decays in two photons. The semileptonic decays are also briefly studied.

Abstract
We study the time dependence of the integrated asymmetries in strangeness of kaons in the decays in two and three pions and in two photons with the purpose of disentangling the CP violating effects in the decay amplitudes from the ones related to the K0-K0BAR mass matrix. We find two cases where they are not reduced by the DELTA-I=1/2 rule or hidden by CP violation in the mass matrix, namely the strangeness-energy correlation of the charged pions in the prompt decay (tau < tau(s)) in pi+ pi--pi-0, and the decays in two photons. The semileptonic decays are also briefly studied.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
