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…
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…
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…
