Abstract The Large Hadron–Electron Collider (LHeC) is designed to move the field of deep
inelastic scattering (DIS) to the energy and intensity frontier of particle physics. Exploiting …

A bstract We make a comparative study of the neutrinoless double beta decay constraints on
heavy sterile neutrinos versus other direct and indirect constraints from both lepton number …

A bstract The future high-energy muon colliders, featuring both high energy and low
background, could play a critical role in our searches for new physics. The smallness of …

Neutrinoless double beta decay (0 ν β β) is a crucial test for lepton number violation.
Observation of this process would have fundamental implications for neutrino physics …

This report summarizes the present status of neutrino non-standard interactions (NSI). After
a brief overview, several aspects of NSIs are discussed, including connection to neutrino …

In this study, we investigate the impact of weakly interacting massive particles (WIMPs) dark
matter (DM) on C–Λ universal relations, GW170817 posterior, and radial oscillations of …

We investigate the possibilities of probing the electroweak scale seesaw scenarios such as
type-I, type-II, and type-III seesaw at e-γ and γ γ colliders. For the case of type-I seesaw, the …

We study the discovery prospect of different three body lepton number violating (LNV)
meson decays M 1-→ ℓ 1-ℓ 2-M 2+ in the framework of the right-handed (RH) neutrino …

We explore the possibility of probing freeze-in dark matter (DM) produced via the right-
handed neutrino (RHN) portal using the RHN search experiments. We focus on a simplified …

Neutrinos are the most elusive particles known. Heavier sterile neutrinos mixing with the
standard neutrinos might solve the mystery of the baryon asymmetry of the universe. In this …
