Loop enhancement of direct detection cross section in a fermionic dark matter model
Khadije Rahi Maleki, Karim Ghorbani
We investigate the effect of one loop quantum corrections on the elastic scattering of dark matter off the nucleon in a fermionic dark matter model. The model introduces two new si…
(sub)GeV Dark Matter in the Higgs Portal Model
Amir Amiri, Bastián Díaz Sáez, Karim Ghorbani
In this research we consider a gauge boson acting as a dark matter candidate. The vector dark matter (DM) gets mass when a complex singlet scalar breaks the gauge symmetry…
The hierarchy problem and the vacuum stability in two-scalar dark matter model
Zohre Habibolahi, Karim Ghorbani, Parsa Ghorbani
We consider an extension to the Standard Model (SM) with two extra real singlet scalars which interact with the SM Higgs particle. The lighter scalar is taken as the dark matter (D…
-Boson Mass Anomaly from Scale Invariant 2HDM
Karim Ghorbani, Parsa Ghorbani
The recently reported measurement of the -boson mass by CDF-II collaboration is significantly heavier than that of the Standard Model prediction. We study this anomaly in the sc…
Scalar Dark Matter with Strong Positron Fluxes
Bastián Díaz Sáez, Karim Ghorbani
We explore a class of simplified extensions to the Standard Model containing a complex singlet scalar as a dark matter candidate accompanied by a vector-like lepton as a mediator,…
Singlet Scalars as Dark Matter and the Muon g-2 Anomaly
Bastián Díaz Sáez, Karim Ghorbani
We explore a simple model containing two singlet scalars as dark matter supplemented with a vector-like lepton. Evading collider and dark matter constraints, the model is able to a…
