Among the places to look for deviations from the SM are new quarks families that can appear as a fourth family with Higgs, a “strong” fourth family without Higgs or vector-like quarks. A potential extension for the SM would be the adjonction a 4th family of heavy chiral fermions that could provide new sources of CP violation to explain the matter-antimatter asymmetry in the Universe, and a ...

The LHC will produce large numbers of top anti-top quark pairs providing an excellent opportunity to study in detail the properties of the top-quark. A possibility that has not been explored experimentally so far is that of CP violating interactions of the top. We discuss the use of T-odd correlations to extract information on the CP violating couplings of the top-quark at the LHC. We illustrate o ... More

LHCb has collected the world's largest sample of charmed hadrons. The ~1 fb–1 sample collected in 2011 is used to search for direct and indirect CP violation in charm, and to measure D0 mixing parameters. Preliminary measurements from several decay modes are presented, with complementary time-dependent and time-integrated analyses. Together, these results significantly improve upon existing me ...

The NA62 experiment at CERN collected a large sample of charged kaon decays with a low intensity beam and minimum bias trigger conditions in 2007. This allowed measurements of a number of rare decays that are difficult to address in conventional high intensity experiments with highly selectivite trigger conditions. In particular, large samples of K+- --> pi gamma gamma and K+- --> e nu gamma dec ... More

CP violation in charmless charged two-body B decays provides a way to measure the CKM angle gamma from decays involving loop diagrams. Using data collected by LHCb in 2011 we reconstruct a large sample of such decay modes of B hadrons. We present measurements of direct CP violation in B(s) → K pi decays, which are the most precise presently available, as well as of direct and mixing-induced CP v ... More

Semileptonic kaon decays offer the most precise determination of the CKM matrix element |Vus|. The experimental precision is however limited by the knowledge of the form factors of this decay, since these enter both the phase space integral and the detector acceptances. The NA48/2 experiment presents new measurements of the form factors of the semileptonic decays of charged kaons, based on ... More

Lepton flavor violating decays such as τ -> μ+ μ- μ+ or B- -> D(*)+ μ- μ- are sensitive probes of New Physics (NP). The discovery of neutrino oscillations implies that at some level there is lepton flavor violation, and in many well motivated extensions of the SM the effects are expected to be visible in τ -> μ+ μ- μ+ decays. LHCb is well suited for this analysis due to the large tau pro ... More

Six lepton flavor violation processes are calcualted in the framework of a model based on the gauge symmetry SU(3)xSU(3)xU(1) (331) without exotic charges in its fermionic spectra. Parameters involved are constraint using the experimental bounds coming from BABAR. Possible implications in the neutrino sector are discussed.

A precision measurement of the helicity-suppressed ratio RK of the K+- --> e+- nu and K+- --> mu+- nu decay rates has been performed using the full data set collected by the NA62 experiment in 2007--2008. The result is in agreement with the Standard Model expectation, and constrains two-Higgs-voublets extension of the Standard Model.

The determination of the CP-violating phase φs in Bs → J/ψ φ decays is one of the key goals of the LHCb experiment.

We present the world’s best measurement of φs and the first observation of a non-zero ∆Γs based upon ~1 fb−1 of data collected at LHCb during 20 ... More

The rare decays B_s(B^0)->mu+mu- and B0->K*mu+mu- are an excellent test of the flavor sector of the Standard Model and provide sensitivity to models with extended Higgs boson sectors.

We construct flavor-dependent chiral U(1)' models with a Z' boson which couples to the right-handed up-type quarks in the standard model. To make the models have realistic renormalizable Yukawa couplings, we introduce new Higgs doublets with nonzero U(1)' charges. Anomaly-free condition can be satisfied by adding extra chiral fermions. We show that these models could analyze the discrepancy betw ... More
