【 摘 要 】

An interesting class of scenarios beyond the Standard Model extends the fermionic content of the theory through the addition of vector-like isosinglet quarks. Through a detailed analysis of available experimental constraints, potential deviations from the Standard Model expectations are addressed in observables such as the time-dependent CP asymmetry in Bs→ J/ΨΦ decays, the D0 same charge dimuon asymmetry in B meson systems AbSL, rare kaon and B decays and deviations from a 3 x 3 unitary mixing matrix.
