We discuss the prospects for observing CP violation in the MSSM with six CP-violating phases, using a geometric approach to maximise CP-violating observables subject to the experimental upper bounds on electric dipole moments. We consider…
CP violation in B decays provides a powerful tool to probe physics from beyond the Standard Model. A theoretical overview of recent developments of benchmark channels is given, ranging from non-leptonic to rare leptonic and semileptonic…
We review the experimental searches and determinations of direct CP violation in meson decays and other systems.
These proceedings introduce the main techniques and ideas for a systematic effective field theory analysis of CP violation in the charged lepton sector. This study is required because the Standard Model of particle physics predicts a very…
The strong CP violation problem has a long history emanating from its discovery 60 years ago in the decay of neutral kaons and subsequent experimental and theoretical studies over several decades. We review herein experimental data that…

The study of $CP$ violation in hyperon transitions has a long history. In the early 2000s the HyperCP experiment made a major effort to seek $CP$-odd signals in the decay sequence $\Xi^-\to\Lambda \pi^-$ and $\Lambda\to p\pi^-$, which…
CP-violating signals in weak $ \Xi\to \pi \Lambda$ decay require the knowledge of $\pi \Lambda$ $S$- and $P$-wave scattering phases at ${m}_{\Xi}$ center-of-mass energy. We have calculated these phases in baryon chiral perturbation theory…
We examine the CP-conserving (CPC) and CP-violating (CPV) effects of a general HZZ coupling through a study of the process H -> ZZ* -> 4 leptons at the LHC. We construct asymmetries that directly probe these couplings. Further, we present…
We search for CP violation in a sample of $4.7\times10^4$ Cabibbo-suppressed $D^0 \to K^+ K^- \pi^+ \pi^-$ decays. We use 470{\rm fb}^{-1} of data recorded by the BaBar detector at the PEPII asymmetric-energy $e^+e^-$ storage rings running…
Some experimental tests are suggested for possible CP-violations for decays of $B^\pm$ bosons. Especially, a detailed comparison of decays $B^+ \rightarrow D^0 \pi^+ \pi^+ \pi^-$ and $B^- \rightarrow \overline{D^0} \pi^- \pi^- \pi^+$ will…
We propose to test $P$- and $CP$-symmetries with the process $e^+e^- \to J/\psi \to \Lambda\bar \Lambda$. The general form of the angular distribution of the process is derived and several observables for the proposed test are introduced.…
The lepton number violation decay $\omega \to \pi^+ \pi^+ e^-e^- +c.c.$ is searched for via $J/\psi \to \omega\eta$ using a data sample of $(1.0087 \pm 0.0044) \times 10^{10}$ $J/\psi$ events collected by the BESIII detector at the BEPCII…
I review several topics involving CP violation with heavy hadrons. In particular, I discuss (i) Hyperons: CP violation in the decay $\Lambda^0 \to p \pi^-$, (ii) Charm: indirect CP violation in the D^0 system, both within and beyond the SM,…
We analyse CP-violating effects in Z \to 4 jet decays, assuming the presence of CP-violating effective $Z b \bar{b} G$ and $Z b \bar{b} G G$ couplings. We discuss the influence of these couplings on the decay width. Furthermore, we propose…
We consider various integrated lepton charge-energy asymmetries and azimuthal asymmetries as tests of CP violation in the process $e^-e^+ \to W^-W^+$. These asymmetries are sensitive to different linear combinations of the CP violating form…
We (re)examine CP violation in the decays B_d -> D K_s, where D represents D^0, D(bar), or one of their excited states. The quantity $\sin^2(2\beta + \gamma)$ can be extracted from the time-dependent rates for $B_d(t) -> {\bar D}^{**0} K_s$…
