I will review the theoretical motivations and experimental signatures for vectorlike fermions.
Vectorlike leptons are an intriguing possibility for physics beyond the Standard Model. We study the reach for discovering or excluding models of vectorlike leptons that mix predominantly with the tau, using multilepton signatures at various future proton-proton collider options: a high-luminosity LHC with Sqrt[s] = 14 TeV, a high-energy collider with Sqrt[s] = 27 TeV, and possible new...
Standard Model Effective Theory (SMEFT) is a powerful tool to constrain new physics in a rather model-independent way. A lot of work has been done to constrain the army of dimension-six operators at next-to-leading order but a rather important subset - four-fermi operators - has been neglected so far. We derive and put into perspective the bounds from the W-polarization fractions associated...
