Abstract
Experimental and theoretical studies of violation in the system are reviewed. Updated predictions for the mixing parameters of the mesons expected in the standard model (SM) are given, namely, the mass difference , the decay rate difference , and the flavor-specific asymmetry and the equivalent quantities in the sector. Current experimental values of and agree with remarkable precision with theoretical expectations. This agreement supports the applicability of theoretical tools such as the heavy quark expansion to these decays. -violating studies in the system provide essential information to test the SM expectations and to unveil a possible contribution of the new physics (NP). NP effects on of the order of 15% are still possible. The phase due to violation in interference of decays and mixing can accommodate effects of the order of . The semileptonic asymmetry due to violation in mixing could still be a factor of 130 larger than its robust SM expectation and thus provides a very clean observable for NP searches. Theoretical improvements that are necessary to make full use of the experimental precision are discussed.
