CP violation measurements at the φ resonance

Flavor Tagging and Cp-violation Measurements at the Tevatron

The CDF collaboration has adapted several heavy flavor tagging techniques and employed them in analyses of time-dependent flavor asymmetries using data from the Tevatron Run I. The tagging algorithms were calibrated using low-Pt inclusive lepton and dilepton trigger data samples. The tagging techniques were applied to a sample of ∼ 400 B d /Bd → J/ψK 0 s decays and were used to measure the CP v...

Recent measurements of CP violation at the B factories

Recent measurements of time dependent CP asymmetries at the B factories have led to substantial progress in our understanding of CP violation. In this article, I review some of these experimental results and discuss their implications in the Standard Model and their sensitivity to New Physics. To be published in Modern Physics Letters A. Work supported in part by Department of Energy contract D...

Prospects for Measurements of Cp Violation at Hadron Colliders

In the Standard Model, CP violation (CPV) arises from the clash of the Yukawa couplings with the charged current interaction. When the Lagrangian is written in the physical (mass) basis, this shows up as an irremovable phase in the CKM 1 quark mixing matrix. The magnitudes of most CKM matrix elements are constrained experimentally , and exhibit an hierarchy, with the magnitudes getting smaller ...

CP violation with B 0 s → D̄ 0 φ decays

We note that it is possible to determine the weak phase γ from the time dependent measurements of the decays B0 s (t)(B̄ 0 s (t)) → D̄0φ without any hadronic uncertainties. These decays are described by the color suppressed tree diagrams and hence are free from the penguin pollutions. We further demonstrate that γ can also be extracted with no hadronic uncertainties from an angular analysis of co...
