Feasible Deviations from Unitarity with Vector-Like Quark Singlets

Francisco Albergaria, Francisco J. Botella, G. C. Branco +2

We deduce pertinent relations between the elements of the CKM matrix, and find that not all of these are totally compatible with experiment and/or the assumption of the SM $3 \time…

Spontaneous CP violation and $μ - τ$ symmetry in two-Higgs-doublet models with flavour conservation

João M. Alves, Francisco J. Botella, Carlos Miró +1

In multi-Higgs-doublet models, requiring simultaneously that (i) CP violation only arises spontaneously, (ii) tree level scalar flavour changing couplings are absent and (iii) the…

What if the Masses of the First Two Quark Families are not Generated by the Standard Higgs?

F. J. Botella, G. C. Branco, M. N. Rebelo +1

We point out that, in the context of the SM, $∣ V_{13}^{2} ∣ + ∣ V_{23}^{2} ∣$ is expected to be large, of order one. The fact that $∣ V_{13}^{2} ∣ + ∣ V_{23}^{2} ∣ \approx 1.6 \times 1 0^{- 3}$ mo…
