Linear Standard Model extensions in the SMEFT at one loop and Tera-Z

Journal of High Energy Physics
Linear Standard Model (SM) extensions, defined as new particles that can couple linearly to SM fields, form a motivated and finite set of simplified models for exploring phenomenology Beyond the SM (BSM).

Electroweak corrections in the SMEFT: four-fermion operators at high energies

Journal of High Energy Physics
In the Standard Model (SM), electroweak (EW) corrections become significant at high energies, particularly at the tera-electronvolt scale and beyond, due to the presence of Sudakov logarithms.
