We confront the new physics models with extra iso-singlet down quarks in the new CP violation experimental era with $\sin{(2\beta)}$ and $\epsilon'/\epsilon$ measurements, $K^+ \to \pi^+ \nu \bar{\nu}$ events, and $x_s$ limits. The…
We extend the range of predictions of the isosinglet (or vector) down quark model to the fully allowed physical ranges, and also update this with the effect of new physics constraints. We constrain the present allowed ranges of sin(2*beta)…
The values of $\sin (2 \alpha)$ and $\sin (2 \beta)$, where $\alpha$ and $\beta$ are angles of the unitarity triangle, will be readily measured in a B factory (and maybe also in hadron colliders). We study the standard model constraints in…
Recent results on B mixing and CP violation from the B-factory experiments, BABAR and Belle are summarized.
Determination of the characteristic CP-violating quantity \sin (2\beta) should be the central goal of a B-meson factory in its first-round experiments. Except the gold-plated channels B_d\to \psi K_S and \psi K_L, three other types of B_d…
In this article I report on new and updated measurements of the CP-violating parameter beta (phi_1), which is related to the phase of the Cabibbo-Kobayashi-Maskawa (CKM) quark-mixing matrix of the electroweak interaction. Over the past few…
Measurements of CP asymmetries in B decays will soon be made at $B$ factories and hadron machines. In light of this, we review and update the profile of the CKM unitarity triangle and the resulting CP asymmetries in B decays. This is done…
The B factories were constructed with a very specific purpose in mind: to test the Cabibbo-Kobayashi-Maskawa description of quark mixing and CP violation in the Standard Model of particle physics. The goals of testing this part of the…
Future asymmetric e+e- --> Upsilon(4S) B factories are being constructed to search for CP violation in B0 decays. It is hoped that a CP asymmetry may be observed in B0-B0bar mixing in analogy with that found in neutral kaons. In this mixing…
In this talk, we first make some brief comments on the phase-convention dependence of the CP-violating parameter \epsilon_B. A simple framework is then presented for analyzing new physics contributions to B^0-\bar{B}^0 mixing and their…
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…
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…
The status of CP violation in $B^0\to \pi^+\pi^-$ and the determination of $\sin 2\phi_2 (\alpha)$ from the $B$ factories is described.
Using the hadronic matrix elements from the lattice, B_K and xi_s, involving only the 4-quark operators for Delta flavor (F) = 2 Hamiltonian relevant for K, B_d and B_s mixing, along with V_cb, we deduce a non-trivial constraint on the SM,…
We explore the would-be consequences of a low value of the CP-violating phase $\sin2\beta_{\psi K}$. The importance of a reference triangle obtained from measurements that are independent of $B$--$\bar B$ and $K$--$\bar K$ mixing is…
Using firmly established experimental inputs such as epsilon_K, Delta M_d, Delta M_s, BR(B -> tau nu), gamma, V_cb along with corresponding lattice matrix elements which have been well studied and are in full QCD such as B_K, SU3 breaking…
We review the salient features of a comparative study of the profile of the CKM unitarity triangle, and the resulting CP-violating phases $\alpha$, $\beta$ and $\gamma$ in B decays, in the standard model and in several variants of the…
We show that the study of CP asymmetries in neutral B-meson decays provides a very sensitive probe of flavour-changing neutral currents (FCNC). We introduce two new angles, $\alpha_{SM}$ and $\beta_{SM}$, whose main feature is that they can…
The constraints on the value of the CKM phase gamma that may be achieved by prospective measurements of sin(2 beta) and sin(2 beta + gamma) are discussed. Significant constraints require quite small errors, and may depend on assumptions…
The status of CP violation and the CKM matrix is reviewed. Direct CP violation in B decay has been established and the measurement of sin(2beta) in \psi K modes reached 5% accuracy. I discuss the implications of these, and of the possible…
