Searching for heavy neutral leptons coupled to axion-like particles at the LHC far detectors and SHiP

Journal of High Energy Physics
In hidden-sector models, axion-like particles (ALPs) can couple to heavy neutral leptons (HNLs), leading to rich phenomenologies. We study ALPs produced from D- and B-meson decays via quark-flavor-violating couplings, and decaying exclusively into a pair

Heavy Neutral Leptons at FASER

, 2018
We study the prospects for discovering heavy neutral leptons at ForwArd Search ExpeRiment (FASER), the newly proposed detector at the LHC. Previous studies showed that a relatively small detector with ~10 m length and ~1 m cross sectional area can probe ...

Second leptogenesis: Unraveling the baryon-lepton asymmetry discrepancy

Journal of High Energy Physics
We propose a novel scenario to explain the matter-antimatter asymmetry by twofold leptogenesis, wherein heavy Majorana neutrinos exhibit temperature-dependent masses and engage in CP-violating decays.

Heavy neutral leptons and top quarks in effective field theory

Journal of High Energy Physics
We study the phenomenology of heavy neutral leptons (HNLs) at the LHC in effective field theory, concentrating on d = 6 operators with top quarks.

Exotic sterile neutrinos and pseudo-Goldstone phenomenology

Journal of High Energy Physics, 2019
We study the phenomenology of a light (GeV scale) sterile neutrino sector and the pseudo-Goldstone boson (not the majoron) associated with a global symmetry in this sector that is broken at a high scale.

Searches for Sterile Neutrinos at Future Electron-Proton Colliders

, 2017
Sterile neutrinos are an attractive extension of the Standard Model of elementary particles towards including a mechanism for generating the observed light neutrino masses.

New physics searches using ProtoDUNE and the CERN SPS accelerator

Journal of High Energy Physics
The exquisite capabilities of liquid Argon Time Projection Chambers make them ideal to search for weakly interacting particles in Beyond the Standard Model scenarios.

Combining Experimental and Cosmological Constraints on Heavy Neutrinos

, 2017
We study experimental and cosmological constraints on the extension of the Standard Model by three right handed neutrinos with masses between those of the pion and W boson.
