We present the study of CP violation in charm and charmonium decays, using a data sample corresponding to 657 \times 10^6 BBbar events collected with the Belle detector at the \Upsilon(4S) resonance at the KEKB asymmetric-energy e^+e^-…

Very recently, the LHCb Collaboration observed the $CP$ violation (CPV) in the charm sector for the first time, with $\Delta A_{CP}^{\rm dir}\equiv A_{CP}(D^0\to K^+K^-)-A_{CP}(D^0\to \pi^+\pi^-)=(-1.54\pm0.29)\times10^{-3}$. This result is…

The CKM paradigm has been tested thoroughly over the last 40 years in both the neutral $K$ and $B$ systems. The recent discovery of neutral charm meson mixing has prompted the search for CP violation in $D$ decays. We discuss the prospects…

The discovery of CP violation in charm sector in 2019 was a milestone in searches performed over last decades. The $\Delta A_{CP}$ measured by LHCb is at the upper end of the Standard Model predictions. This triggers many interpretations…

In this proceeding, I discuss results from the BaBar and Belle collaborations for searches of direct CP violation in the singly Cabibbo-suppressed decay $\D^\pm\to K^+K^-\pi^\pm$ from $e^+e^-$ annihilation data collected at a center-of-mass…

Basic idea of $CP$ violation and its importance for cosmology, Standard Model and possible New Physics are introduced. Recent (2019) discovery of CP violation in charm in the $\Delta A_{CP}$ between $D^0\rightarrow K^-K^+$ and…

The current status of the search for indirect CP violation in the neutral D meson system at the B-factories and at LHCb is reported. The indirect CP asymmetry search is performed by the measurement of the proper-time asymmetry…

Using the full data sample collected with the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we present CP violation in charm decays. The $D^0-\bar{D}^0$ mixing parameter $y_{CP}$ and indirect CP violation parameter…

It was recently pointed out that inclusive B^0(t) decays could show CP violation. The totally inclusive asymmetry is expected to be tiny [O(10^{-3})] because of large cancellations among the asymmetries in the charmless, single charm and…

The discrete symmetries C, P and CP are known to be violated by the weak interaction. It is possible to probe the breaking of these symmetries using asymmetries constructed from triple products based on the decay of some particle M to a…

We propose for the first time a method to perform analysis of time-dependent CP asymmetries in charm by using both, correlated and un-correlated $D^0$ mesons. Here we consider the decay channels $D^0\to K^+ K^-$ and $D^0\to \pi^+ \pi^-$.…

A search for $CP$ and $P$ violation in charmless four-body $B^{0} \to p \bar p K^{+} \pi^{-}$ decays is performed using triple-product asymmetry observables. It is based on proton-proton collision data collected by the LHCb experiment at…

The study of $C\!P$ violation in decays of beauty- and charm-hadrons provides a fundamental test of the predictions of the Standard Model (SM) and represents a sensitive probe to search for physics effects that cannot be described within…

Since the discovery of CP violation more than 5 decades ago, this phenomenon is still attracting a lot of interest. Among the many fascinating aspects of this subject, this review is dedicated to direct CP violation in non-leptonic decays.…

In this talk, I review the various measurements that have been made over the years of CP-violating observables in $B$ decays. These include indirect CP asymmetries, direct CP asymmetries, and triple products. All are discussed in the…

Results of recent searches for new physics in CP violation in charm decays from the BABAR experiment are presented. These results include a measurement of $D^0$ - $\bar{D}^0$ mixing and searches for CP violation in two-body $D^0$ decays, a…

CP-violating asymmetries in charm provide a unique probe of physics beyond the Standard Model. I review several topics relevant to searches for CP-violation in charmed meson and baryon transitions.

Measurements of CKM elements and $CP$-violating observables are sensitive to revealing effects beyond the SM. These proceedings discuss four recent LHCb results. The first one presents $CP$ violation measurements in $B^0_s$ decays.…

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…

The CDF and LHCb experiments have recently provided two intriguing hints for new physics: a large forward-backward asymmetry in $t\bar t$ production, and a direct CP asymmetry in D decays of order a percent. In both cases, flavor…
