Examining the neutrino option
/ Brivio, Ilaria ; Trott, Michael
The neutrino option is a scenario where the electroweak scale, and thereby the Higgs mass, is generated simultaneously with neutrino masses in the seesaw model. [...]

Scheming in the SMEFT. . . and a reparameterization invariance!
/ Brivio, Ilaria ; Trott, Michael
We explain a reparameterization invariance in the Standard Model Effective Field Theory present when considering ψ ¯ ψ → ψ ¯ ψ $$ \overline{\psi}\psi\ \to \overline{\psi}\psi $$ scatterings (with ψ a fermion) and how this leads to unconstrained combinations of Wilson coefficients in global data analyses restricted to these measurements.

On the nonminimal character of the SMEFT
/ Jiang, Yun ; Trott, Michael
When integrating out unknown new physics sectors, what is the minimal character of the Standard Model Effective Field Theory (SMEFT) that can result? In this paper we focus on a particular aspect of this question: “How can one obtain only one dimension six operator in the SMEFT from a consistent tree level matching onto an unknown new physics sector?” We show why this requires conditions on the ultraviolet field content that do not indicate a stand alone ultraviolet complete scenario.
