Following a brief introduction I report the current status of symmetry violation tests from the BaBar experiment, including recent results on the measurement of T violation, and searches for CP and T violation in mixing.

The BABAR experiment at the PEP-II asymmetric B factory at SLAC has collected a large sample of data at the $\Upsilon(4S)$ resonance. I will summarize BABAR's new results on CP violation, B mixing and lifetimes, and a selection of rare B…

The BaBar detector at the PEP-II asymmetric B Factory at SLAC collected a sample of 23M B-anti-B pairs in the years 1999 and 2000. Using this data sample, we measure the amplitude of the time-dependent CP-violating asymmetry in neutral B…

Results by the BaBar and Belle experiments of the measurements $\sin 2\alpha$, $\sin 2\beta$ and $\sin (2\beta + \gamma)$ along with the CKM matrix elements $V_{cb}$ and $V_{ub}$ are presented. The BaBar and Belle experiments $b \to…

An overview of the observation of CP violation in the neutral B system, and the measurements of the CP violating asymmetry sin(2beta) with B to charmonium K^0_{S,L} events, performed by the BaBar and Belle experiments at the SLAC and KEK B…

We present an improved measurement of the standard model CP violation parameter sin2phi_1 (also known as sin2beta) based on a sample of 85 times 10^6 B Bbar pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB…

The BABAR and Belle experiments have made detailed studies of time-dependent CP violation in the B meson sector. If CPT is conserved, CP violation should imply the presence of time-reversal violation. Production of entangled neutral B…

We report the observation of CP violation in the $B^0$ meson system. Using a novel technique for time-dependent measurements, we measure a non-zero value for the CP-violating amplitude $\sin 2\beta$ at the 4.1 $\sigma$ level. We also report…

We summarize the new results on $B$ meson mixing and mixing-related $CP$ violation presented at CKM2016. We place these results in the context of both previous experimental measurements and the most recent theoretical developments in the…

The BABAR detector, operating at energies near the $\Upsilon(4S)$ resonance at the PEP-II asymmetric $B$ Factory at SLAC, has collected a sample of 32 million $B\bar B$ pairs by May 2001. A study of time-dependent CP-violating asymmetries…

Recent results from BaBar and Belle experiments on $B \bar B$ mixing and $\sin 2\phi_1$ are presented. Accuracy of $\Delta m_d$ measurements has reached 1.2%. Higher order effects within the Standard Model or possible new physics effect…

We present measurements from Belle and BABAR of the time-dependent CP-violation parameters S and C in B->eta'K0 decays. Both experiments observe mixing-induced CP violation with a significance of more than 5 standard deviations in this b->…

Recent developments for mixing and CP violation in the D0 and Bs systems are reviewed, including (i) the recently emerging evidence for D0-D0bar mixing and the interpretations of the measurements; (ii) the theoretical status of the…

We review searches for mixing and CP violation in the D0-D0bar system and discuss the first evidence for mixing recently obtained by the Belle and BABAR collaborations. We also present world average values for the mixing parameters x=Delta…
