CP Violation: CKM and Beyond
In the framework of a model with violation of $3\times 3$ unitarity we show that it is possible to accommodate the observed size of the phase in $B^0_s$--$\bar B^0_s$ mixing.
This $3\times 3$ unitarity mixing violation is associated to the presence of a new $Q=2/3$ isosinglet quark $T$ with a mass not exceeding 500 GeV.
The crucial point is the fact that this framework allows for...

We inspect consequences of the latest B_s mixing phase measurements on lepton flavor violation in a supersymmetric SU(5) theory. The O(1) phase, preferring a non-vanishing squark mixing, generically implies tau -> (e + mu) gamma and mu -> e gamma. Depending on the gaugino and the scalar mass parameters as well as tan beta, the rates turn out to be detectable or even already excessive, if the...

Experimental Prospects
LHCb is an experiment which has been designed to make precise measurements of CP violating quantities in B-hadron decays. The scope and experimental challenges of this programme are outlined. Our knowledge of the unitarity triangle will be improved significantly with respect to the present status. In particular, the precision on the angle gamma is expected to improve dramatically. Comparison...

Experimental Prospects
The LHCb experiment will already in 2009 obtain more B-meson decays than has been recorded by any other experiment previously. This provides a unique opportunity for studying very rare decays where the effects of physics beyond the Standard Nodel might be dominating. The decay Bs -> mu+ mu- is very sensitive to an extended Higgs sector and might be the first place to see the effects of new...

Experimental Prospects
The LHCb experiment is designed to perform precision meausrements of CP violation and rare decay searches in the B sector. All subdetectors have been installed and are ready to exploit first data from CERN's Large Hadron Collider. The very first data collected with a minimal interaction trigger should allow the space alignment of the detector to be performed, once enough tracks have been...

Recent measurements of the neutrino of the neutrino and quark mixing angles satisfy the empirical relations called quark lepton complementarity. This empirical data suggests the existence of a correlation between the mixing matrices of neutrinos and quarks. In this work, we examine the possibility that this correlation between the mixing angles of quarks and leptons originates in the similar...
