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 consider the dipole portal to sterile neutrinos, also called heavy neutral leptons (HNLs).
The dipole interaction with the photon leads to HNL production in meson decays as well as …

A bstract We consider the minimal see-saw extension of the Standard Model with two right-
handed singlet fermions N 1, 2 with mass at the GeV scale, augmented by an effective …

We estimate the sensitivity of the DUNE experiment to new physics particles interacting with
neutrinos, considering the dipole portal to heavy neutral leptons and a neutrinophilic scalar …

We revisit models of heavy neutral leptons (neutrissimos) with transition magnetic moments
as explanations of the 4.8 σ excess of electronlike events at MiniBooNE. We first reexamine …

We consider the sterile neutrino, which is also known as heavy neutral lepton, interacting
with the Standard Model (SM) active neutrino and photon via a transition magnetic moment …

In the framework of the low-energy effective theory containing, in addition to the Standard-
Model fields, heavy neutral leptons (HNLs), we compute the decay rates of neutral and …

We discuss the potential of using detectors aimed for searching long-lived particles (LLP) at
the high-luminosity LHC run, to probe the neutrino dipole models. This is achieved by taking …

A bstract In this paper, we study the potential of future colliders to explore the parameter
space of heavy neutral leptons (HNLs) through the dipole portal. We consider hadron …

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 …
