Searches for experimental manifestations of CP violation have born much fruit in recent years with the discovery of direct CP violation and the first evidence of CP violation outside of the neutral kaon system. Nevertheless we still know little about CP violation: its origin remains a mystery and there is little hard evidence that it is the sole province of the standard model. Searches for CP v...

Non-standard physics which can be described by effective four fermion interactions may be an additional source of CP violation in the neutrino propagation. We discuss the detectability of such a CP violation at a neutrino factory. We assume the current baseline setup of the international design study of a neutrino factory (IDS-NF) for the simulation. We find that the CP violation from certain n...

CP violation is implemented in the Standard Model (SM) of particle physics via a non-trivial phase in the Cabbibo-Kobayashi-Maskava matrix 1. Dedicated experiments and facilities have been built to check the predictions of the SM for CP violation, e.g. in the Kaon or the B meson sectors. Up to now, no significant deviations have been found. However, the CP violation implemented in the SM is ins...

Time (T) violation can be related with charge-parity (CP) violation through the CPT theorem. The CP violation was discovered experimentally in the K0-meson decays about 35 years ago. The T violating interaction related with the CP violation violates parity as well. However, an extension of the theory beyond the locality of the interactions might violate the CPT theorem. The result of the CPLEAR...

We discuss various implications of recent experimental results concerning CP violation and mixing in K → ππ, B → ψKS , D → Kπ and D → KK decays. 1. Progress in Experiments The study of CP violation is entering a new era. For a long period only a single CP violating observable has been measured [1]: |εK | = 2.27× 10. (1.1) In the near future, however, we will learn the values of CP asymmetries i...

Since the 1964 discovery of KL → π π [1], understanding CP violation has been a major goal of particle physics. Subsequent experiments showed that the dominant mechanism of CP violation in neutral kaons (still the only particle system in which CP violation has been observed) is a small asymmetry between K → K 0 and K 0 → K mixing. This asymmetry, referred to as indirect CP violation, results in...

The origin of CP violation remains a mystery in particle physics. So far, CP -odd signals have been observed only in the kaon systems. To determine the source and nature of CP violation, it is necessary to observe it in several di erent processes. For a number of years theoretical e orts have been made to study it in the weak decays of hyperons belonging to the baryon octet [1{3]. Here, we pres...

We present an overview of CP violation in the Standard Model and Beyond, describing various possible sources of CP violation and how to search for them.

We investigate the extent to which leptonic CP-violation in (3+2) sterile neutrino models leads to different oscillation probabilities for ν̄μ → ν̄e and νμ → νe oscillations at MiniBooNE. We are using a combined analysis of short-baseline (SBL) oscillation results, including the LSND and null SBL results, to which we impose additional constraints from atmospheric oscillation data. We obtain the f...

This lecture provides a general overview of CP violation, emphasizing CP violation in flavour-violating interactions, such as due to the Kobayashi-Maskawa mechanism.
