DOI: 10.1007/jhep08(2024)128
Abstract: In this work, we address the impact of a small lepton number violation on charged lepton electric dipole moments — EDMs. Low-scale seesaw models protected by lepton number symmetry and leading to pseudo-Dirac pairs in… read more here.

DOI: 10.1007/jhep11(2025)136
Abstract: We explore the sensitivity of the Deep Underground Neutrino Experiment (DUNE) to sterile neutrino oscillations within a 3+(pseudo-Dirac pair) framework. We first consider a pair of two sterile neutrinos forming a pseudo-Dirac pair, then we… read more here.

DOI: 10.1103/physrevd.102.015024
Abstract: We examine simple extension of the standard model with a pair of fermions, one singlet and a doublet, in a common thread linking the dark matter problem with the smallness of neutrino masses associated with… read more here.

DOI: 10.1103/physrevd.107.075029
Abstract: It is still unknown whether the mass terms for neutrinos are of Majorana type or of Dirac type. An interesting possibility, known as pseudo-Dirac scheme combines these two with a dominant Dirac mass term and… read more here.

DOI: 10.1103/physrevd.107.083036
Abstract: We study a minimal model of pseudo-Dirac dark matter, interacting through transition electric and magnetic dipole moments. Motivated by the fact that xenon experiments can detect electrons down to $\sim$\,keV recoil energies, we consider $\mathcal{O}$(keV)… read more here.

DOI: 10.1103/physrevd.111.075007
Abstract: Stringent constraints from the dark matter (DM) direct detection experiments can be naturally evaded for a pseudo-Nambu-Goldstone boson (pNGB) DM. We propose a realization of pNGB DM in the context of a left-right symmetric model,… read more here.
