MeV-scale seesaw and leptogenesis
Journal of High Energy Physics, 2021 We study the type-I seesaw model with three right-handed neutrinos and Majorana masses below the pion mass. In this mass range, the model parameter space is not only strongly constrained by the requirement to explain the light neutrino masses, but also ...

Leptogenesis from a U(1) D resonance
Journal of High Energy Physics, 2020 We propose a novel mechanism to realize leptogenesis through the Breit- Wigner resonance of a dark U(1) D gauge boson Z D , which mediates lepton number vi- olating annihilations of dark matter (DM) in the context of the scotogenic model with a U(1) D ...

Beyond the Standard Model physics at CLIC [PDF]
International Journal of Modern Physics A, 2020 A summary of the recent results from CERN Yellow Report on the CLIC potential for new physics is presented. Greater emphasis is put on the direct search for new physics scenarios motivated by the open issues of the Standard Model as well as on interpretations of Standard Model measurements as probes of new physics in the context of effective field ...

Fermiophobic light Higgs boson in the type-I two-Higgs-doublet model
Physics Letters B, 2022 The null results in the new physics searches at the LHC do not exclude a light new particle if the particle is fermiophobic. A good example is the fermiophobic Higgs boson hf in the type-I two-Higgs-doublet model, which occurs if we adopt α=π/2 and the ...

Freeze-in dark matter from secret neutrino interactions
Journal of High Energy Physics, 2020 We investigate a simplified freeze-in dark-matter model in which the dark matter only interacts with the standard-model neutrinos via a light scalar.

Cosmological relaxation through the dark axion portal
Journal of High Energy Physics, 2022 The dark axion portal is a coupling of an axion-like particle to a dark photon kinetically mixed with the visible photon. We show how this portal, when applied to the relaxion, can lead to cosmological relaxation of the weak scale using dark photon ...

Strongly coupled gauge theories towards physics beyond the Standard Model [PDF]
Proceedings of The 40th International Symposium on Lattice Field Theory — PoS(LATTICE2023)Strongly coupled gauge theories provide an ultra-violet realization of new physics models for physics beyond the Standard Model of particle physics arising from composite dynamics.

Neutrinos and collider physics
New Journal of Physics, 2015 We review the collider phenomenology of neutrino physics and the synergetic aspects at energy, intensity and cosmic frontiers to test the new physics behind the neutrino mass mechanism. In particular, we focus on seesaw models within the minimal setup as
