Generic loop effects of new scalars and fermions in b → sℓ+ℓ− and a vector-like 4th generation
A bstractIn this article we investigate in detail the possibility of accounting for the b → sℓ+ℓ− anomalies via box contributions involving with new scalars and fermions. For this purpose, we first
Small violations of 3 × 3 unitarity, the phase in B0s–bar B0s mixing and visible t → cZ decays at the LHC
We show that it is possible to accommodate the observed size of the phase in Bs0?s0 mixing in the framework of a model with violation of 3 ? 3 unitarity. This violation is associated to the presence
Vector-like quarks and New Physics in the flavour sector
We present a detailed analysis of recent flavour data in the framework of a simple extension of the Standard Model, where a Q = 2/3 vector-like isosinglet quark is added to the spectrum. Constraints
Decays of the heavy top and new insights on $$\epsilon _K$$ in a one-VLQ minimal solution to the CKM unitarity problem
<jats:p>We propose a minimal extension of the Standard Model where an up-type vector-like quark, denoted <jats:italic>T</jats:italic>, is introduced and provides a simple solution to the CKM

CP Violation in the Renormalizable Theory of Weak Interaction
In a framework of the renormalizable theory of weak interaction, problems of CP-violation are studied. It is concluded that no realistic models of CP-violation exist in the quartet scheme without
A basis independent formulation of the connection between quark mass matrices, CP violation and experiment
In the standard eletroweak model, with three families, a one-to-one correspondence between certain determinants involving quark mass matrices (m andm′ for charge 2/3 and −1/3 quarks respectively) and
Constraints on the mixing of a fourth family of quarks.
TLDR
The constraints on the mixing of a possible fourth family of quarks are studied and an abundant rate of same-sign dileptons at UPSILON(4S) if the fourth up-type quark is sufficiently heavy is found.
