Symmetry studies represent one of the most promising frontiers in particle physics research. This investigation focuses on exploring $P$ and $CP$ symmetries in the charm system through the measurement of asymmetry decay parameters in the…

We measure the direct CP-violating parameter A_CP for the decay of the charged charm meson, D+ -> K-pi+pi+ (and charge conjugate), using the full 10.4 fb-1 sample of ppbar collisions at sqrt(s) = 1.96 TeV collected by the D0 detector at the…

There is growing evidence for deviation from the standard model predictions in the ratios between semi-tauonic and semi-leptonic $B$ decays, known as the $R(D^{(*)})$ puzzle. If the source of this non-universality is new physics, it is…

We review and update the constraints on the parameters of the quark flavour mixing matrix $V_{CKM}$ in the standard model and estimate the resulting CP asymmetries in $B$ decays, taking into account recent experimental and theoretical…

We review recent experimental results on D0 -D0bar mixing and CP violation charm decays. These studies provide complementary constraints on many different extensions of the Standard Model. Observation of CP violation in charm decays at the…

We search for CP violation in a sample of 4.7x10^4 Cabibbo suppressed D0 -> K+K-pi+pi- decays. We use 470 fb-1 of data recorded by the BaBar detector at the PeP2 asymmetric-energy e+e- storage rings running at center-of-mass energies near…

The Standard Model contains a natural source for CP asymmetries in weak decays, which is described by the KM mechanism. Beyond $\epsilon _K$ it generates only elusive manifestations of CP violation in {\em light-}quark systems. On the other…

We present the current status of experimental results and prospects for the determination of CP and T violation in the charm sector. Such measurements have acquired renewed interest in recent years in view of theoretical work, which has…

Indirect CP violation in the $D^0$ system can be probed by measuring the parameter $A_{\Gamma}$, defined as the CP asymmetry of the effective lifetime of the $D^0$ meson decaying to a CP eigenstate. This can be significantly enhanced beyond…

CP violation in K and B decays is reviewed in the Standard Model (SM) and beyond the SM. In K decays, one is seeking first evidence for CP violation in direct $K\to \pi\pi$ decays. This would not give a precise quantitative test for the…

A search for decay-time-dependent charge-parity ($CP$) asymmetry in $D^0 \to K^+K^-$ and $D^0 \to \pi^+\pi^-$ decays is performed at the LHCb experiment using proton-proton collision data recorded at a center-of-mass energy of 13TeV, and…

The first study is presented of CP violation with an amplitude analysis of the Dalitz plot of $B^0 \to D K^+ \pi^-$ decays, with $D \to K^+ \pi^-$, $K^+ K^-$ and $\pi^+ \pi^-$. The analysis is based on a data sample corresponding to…

Searches for CP violation in the charm sector from the E791, FOCUS, CLEO, BABAR and BELLE experiments are presented. Most analyses consider CP violation in two-body or quasi-two-body decays. Preliminary results from CLEO and FOCUS using…

$D$ meson decays into neutral kaons involve both Cabibbo-favored and doubly Cabibbo-suppressed amplitudes as well as final-state kaon mixing, providing abundant sources of CP violation. In this work, we analyze CP asymmetries in the $D\to…

Decays of b-hadrons are the ideal place to perform measurements of CP violation. Many decay channels allow to over-constrain the unitarity triangles of the CKM matrix and test the SM hypothesis that a single phase is the origin of all CP…

Recently, the large CP asymmetries in $B^\pm\to\pi^\pm\pi^+\pi^-$ decays were found by the LHCb Collaboration to localize in the region $m_{\pi^+\pi^-}^2<0.4 \text{GeV}^2$. We find such large localized CP asymmetries may be due to the…

Our knowledge of flavour dynamics has undergone a `quantum jump' since just before the turn of the millenium: direct CP violation has been firmly established in $K_L \to \pi \pi$ decays in 1999; the first CP asymmetry outside $K_L$ decays…

Current HFAG averages of the mixing and CP violation parameters in the $D^0$ meson system is to be reviewed. We present recent Belle measurements of the mixing parameters $x$ and $y$ using $D^0\rightarrow K^0_S\pi^+\pi^-$, and $y_{CP}$ and…

Generically, non-Standard-Model particles contribute to processes with order-one charge-parity (CP) violating phases, as CP is not a fundamental symmetry of nature. The exploration of CP violation becomes therefore a sensitive search for…

We study rare exclusive B decays based on the quark-level transition b->s(d)l^+l^-, where l=e or mu, in the context of supersymmetric theories with minimal flavour violation. We present analytic expressions for various mixing matrices in…
