We show that the CP-violating effect in K^0 vs \bar K^0-->\pi^+\pi^-\pi^0 decays differs from that in K_{\rm L}-->\pi^+\pi^-, K_{\rm L}-->\pi^0\pi^0 or the semileptonic K_{\rm L} transitions, if there exists CPT violation in K^0-\bar{K}^0…
A search is presented for CPT-violating effects in the mixing of $B^0_s$ mesons using the D0 detector at the Fermilab Tevatron Collider. The CPT-violating asymmetry in the decay $B^0_s \rightarrow \mu^{\pm} D_s^{\mp} X$ as a function of…
In this review we first discuss the theoretical motivations for possible CPT violation and deviations from ordinary quantum-mechanical behavior of field-theoretic systems in the context of an extended class of quantum-gravity models. Then…
The CP violation phase phi_s and charge asymmetries in B^0_s decays have been measured by the D0 experiment in Run II of the Fermilab Tevatron Collider where proton anti-proton collisions take place at a center of mass energy of…
We present a series of measurements based on K -> pi+pi- and K -> pi0pi0 decays collected in 1996-1997 by the KTeV experiment (E832) at Fermilab. We compare these four K -> pipi decay rates to measure the direct CP violation parameter…
In this decade, the exploration of CP violation is governed by the B-meson system, where non-leptonic decays play an outstanding role. To set the stage, we have first a look at the main strategies to circumvent the calculation of the…
The CKM collaboration is proposing to measure the branching ratio of the rare K decay (K+ --> pi+ nu nubar) at the Main Injector at Fermilab. Our goal is to be able to observe about 100 events, for a Standard Model branching ratio of about…
We have compared the decay rates of K_L and K_S to \pi^+ \pi^- and \pi^0 \pi^0 final states using a subset of the data from the KTeV experiment (E832) at Fermilab. We find that the direct-CP-violation parameter Re(\epsilon'/\epsilon) is…
Using pp collision data, corresponding to an integrated luminosity of $1.0 \mathrm{fb}^{-1}$, collected by LHCb in 2011 at a center-of-mass energy of 7 TeV, we report the measurement of direct CP violation in $B^0_s \to K^-\pi^+$ decays,…
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…
Measurements of the CKM parameter $\sin(2 \beta)$ have established $CP$ violation in the $B^0$ meson system arising from the interference between mixing and decay. However, direct CP violation, arising from the interference among different…
The $K \rightarrow \mu\mu$ decays have recently been identified as another golden kaon physics mode alongside the rare $K \rightarrow\pi\nu\bar{\nu}$ processes. These golden modes provide precision tests of the Standard Model with very high…
Experimental prospects for observing CP violation in B-meson decays are reviewed. Comparisons are made for various options: experiments at $e^+ e^-$ B-Meson Factories, HERA and the TEVATRON will produce results in near future. They will…
As it is very promising to expect a discovery of CP violation in the leptonic sector, the precision measurement of the Dirac CP phase $\delta_\text{CP}$ is going to be one of the key interests in the future neutrino oscillation experiments.…
We present a measurement of relative partial widths and decay rate CP asymmetries in $K^-K^+$ and $\pi^-\pi^+$ decays of $\Do$ mesons produced in $p\bar{p}$ collisions at $\sqrt{s} = 1.96 \TeV$. We use a sample of $2\times10^5$…
We analyze the New Physics sensitivity of a recently proposed method to measure the CP-violating ${\cal B}(K_S\to\mu^+\mu^-)_{\ell=0}$ decay rate using $K_S - K_L$ interference. We present our findings both in a model-independent EFT…
The discovery of leptonic CP violation is one of the primary goals of next-generation neutrino oscillation experiments, which is feasible due to the recent measurement of a relatively large leptonic mixing angle \theta_{13}. We suggest two…
