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 effects …

The muon magnetic anomaly, a μ=(g μ− 2)/2, plays a special role in the history of the
Standard Model (SM). Precise calculations and measurements of this fundamental quantity …

The new CDF II measurement of W-boson mass shows a 7 σ deviation from the standard
model (SM) prediction, while the recent FNAL measurement of the muon g-2 shows a 4.2 σ …

A bstract The recent confirmation by the Fermilab-based Muon g-2 experiment of the (g− 2) μ
anomaly has important implications for allowed particle spectra in softly broken …

The field of particle physics is at the crossroads. The discovery of a Higgs-like boson
completed the Standard Model (SM), but the lacking observation of convincing resonances …

The CDF Collaboration has recently reported an updated result on the W-boson mass
measurement, showing a 7 σ deviation from the standard model prediction. The discrepancy …

A bstract We comprehensively study all viable new-physics scenarios that resolve the muon
(g− 2) μ anomaly with only Standard Model singlet particles coupled to muons via …

The recent measurement of the muon anomalous magnetic moment a μ≡(g− 2) μ/2 by the
Fermilab Muon g− 2 experiment sharpens an earlier discrepancy between theory and the …

We discuss the minimal theory for quark-lepton unification at the low scale. In this context,
the quarks and leptons are unified in the same representations and neutrino masses are …

A program to build a lepton-collider Higgs factory, to precisely measure the couplings of the
Higgs boson to other particles, followed by a higher energy run to establish the Higgs self …
