Constraining new physics effective interactions via a global fit of electroweak, Drell-Yan, Higgs, top, and flavour observables
J. de Blas, A. Goncalves, V. Miralles +3
We present results from a global fit of Standard Model parameters and dimension-6 SMEFT Wilson coefficients that includes electroweak, Drell-Yan, Higgs-boson, top-quark, and flavou…

How large can lepton mixing be?
J. de Blas, C. Giuliano, G. Guedes +2
We show that, contrary to common expectations, the observed charged leptons can have a substantial mixing with new heavier fermions, at the level of 20. This can happen, in the…

A detailed study on the prospects for a threshold scan in collisions
Matteo M. Defranchis, Jorge de Blas, Ankita Mehta +2
A scan of the beam energy across the top quark pair () production threshold is part of the program of future Higgs, top, and electroweak factory projects. I…
