CP-Violation
Parallel contribution
I will review the present status of CP violating observables in low energy observables and the progress in their precision that can be expected for in the future. I will discuss what deviations from Standard Model can potentially teach us about new physics and also discuss recent hints of non-Standard Model CP violating sources in heavy quark transitions.

We present an improved measurement of the charge asymmetry $A$ of like-sign
dimuon events in 9 fb$^{-1}$ of $p\overline{p}$ collisions recorded with the
D0 detector at a center-of-mass energy $\sqrt{s} = 1.96$ TeV at the
Fermilab Tevatron collider. From $A$, we extract the like-sign dimuon
charge asymmetry in semileptonic $b$-hadron decays. We also study the
dependence of charge asymmetry...

In this talk, I will discuss T-odd correlations induced by CP violating anomalous top-quark couplings at both production and decay level in the context of the Tevatron and the Large hadron collider. We will also show that by simply making use of four momenta of the top decay products it is possible to isolate such effects. With specific examples of top decay modes the experimental...

The role of lattice matrix elements in refined tests of the Standard Model and for search of new physics will be discussed. Although the results from the lattice in conjunction with data from B-factories provided a confirmation of the CKM-paradigm of CP violation a few years ago, since then improved calculations and better data
from experiments is now yielding strong indications that the...

The Bs meson is studied with the CMS detector at LHC.
The time-dependent measurements of the Bs decay into
J/Psi Phi and of the rate of the rare decay into mu mu
potentially provide indirect constraints on physics
beyond the Standard Model. This talk presents the first
cross section measurement for Bs->J/Psi phi production
based on data taken in 2010 and discusses prospects of
the...

The determination of the mixing induced CP-violating asymmetry in
decays such as $B^0_s \to J/\psi \phi$ is one of the key goals
of the LHCb experiment.
Its value is predicted to be very small in the Standard Model but
can be significantly enhanced in many models of New Physics.
The steps towards a precise determination of this phase with a
flavour-tagged, time-dependent, angular...

Parallel contribution
We report a new measurement of the $CP$-violating phase $\phi_s$, of the decay width difference for the two mass eigenstates $\Delta \Gamma_s$, of the mean $B^0_s$ lifetime $\overline{\tau}_s$, and of magnitudes of the decay amplitudes, from the flavor-tagged decay $B^0_s\to J/\psi \phi$. For the first time, we consider possible contributions from the decay $B^0_s \rightarrow J/\psi K^+K^-$,...

Parallel contribution
The CP asymmetry in inclusive b-> s gamma decays is an important probe of new physics. The theoretical prediction was thought to be of a perturbative origin. In the standard model the perturbative prediction for the asymmetry is about 0.5 percent. In a recent work with M. Benzke, S.J. Lee and M. Neubert , we have shown that the asymmetry is in fact dominated by non-perturbative effects. Since...

Parallel contribution
We report the first measurement of branching fractions and CP-violating asymmetries
of doubly-Cabibbo suppressed B+ --> D0 K decays in hadron collisions, using the approach proposed
by Atwood, Dunietz, and Soni (ADS) to determine the CKM angle gamma in 7.0 fb-1 of data.
The ADS parameters are determined with accuracy comparable with B factory measurements.

We report on the study of the decay B+ ->D0(D0bar) K+ where the D0 or D0bar decaying to Kpipi0, with the Atwood Dunietz and Soni (ADS) method. We measure the ratios Rads, R+, and R- that, since the processes B+ -> D0barK+ and B+ -> D0K+ are proportional to Vcb and Vub, respectively, are sensitive to rB and to the weak phase gamma. We also report the results of CP violation studies of B->Dcp...

We present the final measurement of time-dependent CP violation in
the neutral B decays into charmonium and a K^0 meson with a large
data sample containing 772 million B \bar{B} pairs collected at the
Upsilon(4S) resonance with with the Belle detector at the KEKB
asymmetric-energy e+e- collider. We also reports the first results
on CP violation in the radiative penguin decay B^0->K_S phi...

Parallel contribution
We study a new type of CP violating observable that arises in three body decays. We consider decays that are dominated by an intermediate resonance that can go on shell. In many cases, the decay can occur via two different orderings. The required CP-even phase arises due to the different virtualities of the resonance in the two diagrams corresponding to these orderings. This method can be...

We present the first evidence for B->D K, D->K^+ pi^- and
measurements of related observables used in the Atwood-Dunietz-Soni
(ADS) method to determine the CKM parameter phi_3 (also known as
gamma). Measurement of related B->D^* K^- modes are also reported.
We report the first measurement of phi_3 using model-independent
analysis of the Dalitz plot of B->D K, D->K_S^0 pi^+ pi^-.
