The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

Abstract The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep
inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting …

Sterile neutrinos are among the most attractive extensions of the SM to generate the light
neutrino masses observed in neutrino oscillation experiments. When the sterile neutrinos …

A bstract The existence of right-handed neutrinos, or heavy neutral leptons (HNLs), is
strongly motivated by the observation of neutrino masses and mixing. The mass of these …

We revisit the effective field theory of the standard model that is extended with sterile
neutrinos, N. We examine the basis of complete and independent effective operators …

A bstract Heavy neutral leptons (HNLs) with masses around the electroweak scale are
expected to be rather long-lived particles, as a result of the observed smallness of the active …

A bstract If neutrinos are Dirac particles and, as suggested by the so far null LHC results, any
new physics lies at energies well above the electroweak scale, the Standard Model effective …

A bstract In this work we consider the Standard Model Effective Field Theory extended with
right-handed neutrinos, the νSMEFT, and calculate the full set of one-loop anomalous …

A bstract Future electron-proton collider proposals like the LHeC or the FCC-eh can supply
ab− 1 of collisions with a center-of-mass energy in the TeV range, while maintaining a clean …

A bstract We study ultra-violet completions for operators in standard model effective field
theory extended with right-handed neutrinos (NR SMEFT). Using a diagrammatic method …
