Probing the dipole portal to heavy neutral leptons via meson decays at the high-luminosity LHC
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 …

Neutrino spin-flavour precession in magnetized white dwarf
Due to notoriously small value of the neutrino magnetic moment, the phenomena of neutrino
spin flavour precession (SFP) require a very high magnetic field. This makes only a handful …
