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…
Neutrino Theory in the Precision Era
Asmaa Abada, Gabriela Barenboim, Toni Bertólez-Martínez +76
This document summarises discussions on future directions in theoretical neutrino physics, which are the outcome of a neutrino theory workshop held at CERN in February 2025. The st…
Vector-like quark doublets, weak-basis invariants and CP violation
F. Albergaria, J. F. Bastos, B. Belfatto +4
We study Standard Model extensions with isodoublet vector-like quarks with standard charges. Their presence induces right-handed charged and neutral currents. We identify minimal s…
Vector-like Singlet Quarks: a Roadmap
João M. Alves, G. C. Branco, A. L. Cherchiglia +5
We review the theory and phenomenology of isosinglet vector-like quarks (VLQs). In recent years, interest in VLQs has been increasing, due to their contributions to new physics eff…
CP-odd and CP-even Weak-Basis Invariants in the Presence of Vector-Like Quarks
Francisco Albergaria, G. C. Branco, José Filipe Bastos +1
We propose a minimal set of weak-basis invariants in an extension of the SM where one up-type isosinglet vector-like quark is introduced, which allows us to obtain all the physical…
Type-I Seesaw with eV-Scale Neutrinos
G. C. Branco, J. T. Penedo, Pedro M. F. Pereira +2
We consider seesaw type-I models including at least one (mostly-)sterile neutrino with mass at the eV scale. Three distinct situations are found, where the presence of light extra…
