Pseudo-scalar dark matter from a broken gauged symmetry
Junho Kang, Sarif Khan, Jongkuk Kim +1
We propose a novel model for pseudo-scalar dark matter (PSDM) by extending the Standard Model (SM) with a dark gauged symmetry, but without dark charged fermions. We impos…
Baryogenesis and Dark Matter from non-thermally produced WIMPs
Giorgio Arcadi, Sarif Khan, Agnese Mariotti
We illustrate, via a simplified model, a scenario in which the baryon-asymmetry and, possibly the dark matter component of the Universe are simultaneously generated by the decay of…
WIMP-FIMP option and neutrino masses via a novel anomaly-free B-L symmetry
Sarif Khan, Hyun Min Lee
We propose a novel model with singlet dark matter fermions composed of WIMP and FIMP, which is anomaly-free without a need for introducing right-handed neutrinos. Ferm…
Constraining dark matter from strong phase transitions in a model: Implications for neutrino masses and muon
Sandhya Choubey, Sarif Khan, Marco Merchand +1
In this paper, we study a non-minimal gauged model, where we add two complex singlet scalars, three right-handed Majorana neutrinos (RHN), and a vector-like dark f…
WIMP and FIMP Dark Matter in Singlet-Triplet Fermionic Model
Geneviève Bélanger, Sandhya Choubey, Rohini M. Godbole +3
We present an extension of the SM involving three triplet fermions, one triplet scalar and one singlet fermion, which can explain both neutrino masses and dark matter. One triplet…
Axion and FIMP Dark Matter in a extension of the Standard Model
Laura Covi, Sarif Khan
In the Standard Model a Dark Matter candidate is missing, but it is relatively simple to enlarge the model including one or more suitable particles. We consider in this paper one s…
A Two-Component Dark Matter Model and its Associated Gravitational Waves
Francesco Costa, Sarif Khan, Jinsu Kim
We consider an extension of the Standard Model that accounts for the muon tension and neutrino masses and study in detail dark matter phenomenology. The model under considera…
and strongly interacting dark matter with collider implications
Anirban Biswas, Sarif Khan
The quest for new physics beyond the Standard Model is boosted by the recently observed deviation in the anomalous magnetic moments of muon and electron from their respective theor…
Zooming in on eV-MeV Scale Sterile Neutrinos in light of Neutrinoless Double Beta Decay
Tapoja Jha, Sarif Khan, Manimala Mitra +1
The existence of light sterile neutrinos, as predicted in several models, can help to explain a number of observations starting from dark mater to recent anomalies in short baselin…
Right Handed Neutrinos, TeV Scale BSM Neutral Higgs and FIMP Dark Matter in EFT Framework
Geneviève Bélanger, Sarif Khan, Rojalin Padhan +2
We consider an effective field theory framework with three standard model (SM) gauge singlet right handed neutrinos, and an additional SM gauge singlet scalar field. The framework…
Explaining Xenon-1T signal with FIMP dark matter and neutrino mass in a extension
Sarif Khan
In the present work, we have extended the standard model by an abelian gauge group and additional particles. In particular, we have extended the particle content by thre…
Two component FIMP DM in a extension of the SM
Waleed Abdallah, Sandhya Choubey, Sarif Khan
In this work, we discuss two component fermionic FIMP dark matter (DM) in a popular extension of the standard model (SM) with inverse seesaw mechanism. Due to the introduced…
Same-Sign Tetralepton Signature at Large Hadron Collider, and future Collider
Eung Jin Chun, Sarif Khan, Sanjoy Mandal +2
We analyze a novel signature of the type II seesaw model - same-sign tetra-lepton signal arising from the mixing of neutral Higgs bosons and their subsequent decays to singly and d…
FIMP dark matter candidate(s) in a model with inverse seesaw mechanism
Waleed Abdallah, Sandhya Choubey, Sarif Khan
The non-thermal dark matter (DM) production via the so-called freeze-in mechanism provides a simple alternative to the standard thermal WIMP scenario. In this work, we consider a p…
Doubly-charged Higgs Boson at Future Electron-Proton Collider
P. S. Bhupal Dev, Sarif Khan, Manimala Mitra +1
We explore the discovery prospect of the doubly-charged component of an -triplet scalar at the future collider FCC-eh, proposed to operate with an electron beam en…
Common origin of baryon asymmetry, dark matter and neutrino mass
Anirban Biswas, Sandhya Choubey, Laura Covi +1
In this work, we explain three beyond standard model (BSM) phenomena, namely neutrino masses, the baryon asymmetry of the Universe and Dark Matter, within a single model and in eac…
Neutrino and Collider Implications of a Left-Right Extended Zee Model
Sarif Khan, Manimala Mitra, Ayon Patra
We study a simple left-right symmetric (LRS) extension of the Zee model for neutrino mass generation. An extra singlet charged scalar helps in generating a loop-induc…
Inverse seesaw and dark matter in a gauged extension with flavour symmetry
Anirban Biswas, Sandhya Choubey, Sarif Khan
We propose a model which generates neutrino masses by the inverse seesaw mechanism, provides a viable dark matter candidate and explains the muon () anomaly. The Standard Mode…
Singlet-Triplet Fermionic Dark Matter and LHC Phenomenology
Sandhya Choubey, Sarif Khan, Manimala Mitra +1
It is well known that for the pure standard model triplet fermionic WIMP-type dark matter (DM), the relic density is satisfied around 2 TeV. For such a heavy mass particle, the pro…
Explaining the 3.5 keV X-ray Line in a Extension of the Inert Doublet Model
Anirban Biswas, Sandhya Choubey, Laura Covi +1
We explain the existence of neutrino masses and their flavor structure, dark matter relic abundance and the observed 3.5 keV X-ray line within the framework of a gauged $U(1)_{L_μ…
Neutrino Mass, Leptogenesis and FIMP Dark Matter in a Model
Anirban Biswas, Sandhya Choubey, Sarif Khan
The Standard Model (SM) is inadequate to explain the origin of tiny neutrino masses, the dark matter (DM) relic abundance and also the baryon asymmetry of the Universe. In this wor…
FIMP and Muon () in a U Model
Anirban Biswas, Sandhya Choubey, Sarif Khan
The tightening of the constraints on the standard thermal WIMP scenario has forced physicists to propose alternative dark matter (DM) models. One of the most popular alternate expl…
