CP Violation in the K0 System
A small matter-antimatter asymmetry of the weak force was experimentally established. This CP violation may be related to the small excess of matter from the big bang. The nature of CP violation in the K system has been clarified after 35 years of experimentation: it is due to a small part of the weak interaction (“illiweak interaction”). A non-trivial phase in the weak quark mixing matrix gene...
متن کاملCp Violation in the K-system
CP violation in the K system is pedagogically reviewed. We discuss its manifestations in the neutral K meson systems, in rare K meson decays and in decays of charged K mesons. Results from classical experiments, and perspectives for upcoming experiments are included. We also briefly discuss the possibility of CPT tests.

متن کاملIndirect Cp Violation in the B - System
We show that, contrary to the flavour mixing amplitude q/p, both Re(ε) and Im(ε) are observable quantities, where ε is the phase-convention-independent CP mixing. We consider semileptonic B d decays from a CP tag and build appropriate time-dependent asymmetries to separate out Re(ε) and Im(ε). " Indirect " CP violation would have in Im(ε)/(1 + |ε| 2) its most prominent manifestation in the B-sy...
متن کاملCP violation in the B system.
The phenomenon of CP violation is crucial to understand the asymmetry between matter and antimatter that exists in the Universe. Dramatic experimental progress has been made, in particular in measurements of the behaviour of particles containing the b quark, where CP violation effects are predicted by the Kobayashi-Maskawa mechanism that is embedded in the standard model. The status of these me...
متن کاملCp Violation
Three possibilities for the origin of CP violation are discussed: (1) the Standard Model in which all CP violation is due to one parameter in the CKM matrix, (2) the superweak model in which all CP violation is due to new physics and (3) the Standard Model plus new physics. A major goal of B physics is to distinguish these possibilities. CP violation implies time reversal violation (TRV) but di...
