A two-component dark matter model and its associated gravitational waves

F Costa, S Khan, J Kim - Journal of High Energy Physics, 2022 - Springer
A bstract We consider an extension of the Standard Model that accounts for the muon g− 2
tension and neutrino masses and study in detail dark matter phenomenology. The model …

Two component dark matter with inert Higgs doublet: neutrino mass, high scale validity and collider searches

S Bhattacharya, P Ghosh, AK Saha, A Sil - Journal of High Energy Physics, 2020 - Springer

allowed parameter space from high scale validity (absolute stability of Higgs vacuum and …

Shining dark matter in Xenon1T

G Paz, AA Petrov, M Tammaro, J Zupan - Physical Review D, 2021 - APS
We point out that a nonrelativistic approximately 2 GeV dark matter (DM) which interacts with
visible matter through higher-dimensional Rayleigh operators could explain the excess of …

Two dark matter candidates: The case of inert doublet and singlet scalars

G Belanger, A Mjallal, A Pukhov - Physical Review D, 2022 - APS
We consider a multicomponent dark matter model where the dark sector contains a scalar
doublet and a complex scalar singlet. We impose a discrete Z 4 symmetry to ensure such …

TeV scale leptogenesis with dark matter in non-standard cosmology

D Mahanta, D Borah - Journal of Cosmology and Astroparticle …, 2020 - iopscience.iop.org
We study the consequence of a non-standard cosmological epoch in the early universe on
the generation of baryon asymmetry through leptogenesis as well as dark matter …

Electroweak phase transition and gravitational waves in a two-component dark matter model

A Mohamadnejad - Journal of High Energy Physics, 2022 - Springer
A bstract We investigate an extension of the Standard Model (SM) with two candidates for
dark matter (DM). One of them is a real scalar field and the other is an Abelian gauge field …

Connecting light dirac neutrinos to a multi-component dark matter scenario in gauged model

D Nanda, D Borah - The European Physical Journal C, 2020 - Springer
We propose a new gauged BL BL extension of the standard model where light neutrinos are
of Dirac type, naturally acquiring sub-eV mass after electroweak symmetry breaking, without …

Spontaneous leptogenesis with sub-GeV axionlike particles

A Datta, SK Manna, A Sil - Physical Review D, 2024 - APS
A derivative coupling of an axionlike particle (ALP) with a BL current may lead to the baryon
asymmetry of the Universe via spontaneous leptogenesis provided a lepton number …

Multicomponent dark matter in extended U (1) B− L: neutrino mass and high scale validity

S Bhattacharya, N Chakrabarty… - Journal of Cosmology …, 2020 - iopscience.iop.org
Standard Model with right handed neutrinos charged under additional U (1) B− L gauge
symmetry offer solutions to both dark matter (DM) problem and neutrino mass generation …

Type III seesaw for neutrino masses in U (1) B− L model with multi-component dark matter

A Biswas, D Borah, D Nanda - Journal of High Energy Physics, 2019 - Springer
A bstract We propose a B− L gauged extension of the Standard Model where light neutrino
masses arise from type III seesaw mechanism. Unlike the minimal B− L model with three …
