Light Dark Matter Candidate in B-L Gauged Radiative Inverse Seesaw

TL;DR

This paper explores a B-L gauged radiative inverse seesaw model where a real bosonic particle in the 1-80 GeV range could serve as dark matter, aligning with experimental signals from CoGeNT and XENON.

Contribution

It introduces a more general neutrino mass structure in a B-L symmetric inverse seesaw model and investigates its dark matter candidate in the GeV mass range.

Findings

Dark matter candidate in 1-80 GeV range compatible with experiments.

Extended neutrino mass structure beyond previous models.

Potential explanation for signals observed by CoGeNT and XENON.

Abstract

We study a radiative inverse seesaw model with local B-L symmetry, in which we extend the neutrino mass structure that is generated through a kind of inverse seesaw framework to the more generic one than our previous work. We focus on a real part of bosonic particle as a dark matter and investigate the features in O(1-80) GeV mass range, reported by the experiments such as CoGeNT and XENON (2012).
