Experimental and theoretical studies of CP violation in the B s 0 system are reviewed.
Updated predictions for the mixing parameters of the B s 0 mesons expected in the standard …

In the past decade, one of the major challenges of particle physics has been to gain an in-
depth understanding of the role of quark flavor. In this time frame, measurements and the …

We present an up-to-date profile of the Cabibbo-Kobayashi-Maskawa matrix with emphasis
on the interpretation of recent CP-violation results from the B factories. For this purpose, we …

CMS is a general purpose experiment, designed to study the physics of pp collisions at 14
TeV at the Large Hadron Collider (LHC). It currently involves more than 2000 physicists from …

We update the theory predictions for the mass difference ΔM s, the width difference ΔΓ s and
the CP asymmetry in flavour-specific decays, a fs s, for the B s− bar B s system. In particular …

We update the constraints on new-physics contributions to ΔF= 2 processes from the
generalized unitarity triangle analysis, including the most recent experimental …

From an analysis of the flavor-tagged decay B s 0→ J/ψ ϕ we obtain the width difference
between the B s 0 light and heavy mass eigenstates, Δ Γ s= 0.19±0.07 (stat)-0.01+ 0.02 …

We report an updated measurement of the CP-violating phase, ϕ s J/ψ ϕ, and the decay-
width difference for the two mass eigenstates, Δ Γ s, from the flavor-tagged decay B s 0→ J/ψ …

This Letter describes the first determination of bounds on the CP-violation parameter 2 β s
using B s 0 decays in which the flavor of the bottom meson at production is identified. The …

The presence of a sizable CP-violating phase in B s− B s mixing would be an unambiguous
signal of physics beyond the standard model. We analyze various possibilities to detect such …
