Scalar Dark Matter in Scale Invariant Standard Model
Karim Ghorbani, Hossein Ghorbani
We investigate single and two-component scalar dark matter scenarios in classically scale invariant standard model which is free of the hierarchy problem in the Higgs sector. We sh…
Two-portal Dark Matter
Karim Ghorbani, Hossein Ghorbani
We propose a renormalizable dark matter model in which a fermionic dark matter (DM) candidate communicates with the standard model particles through two distinct portals: Higgs and…
Scalar Split WIMPs in the Future Direct Detection Experiments
Karim Ghorbani, Hossein Ghorbani
We consider a simple renormalizable dark matter model consisting of two real scalars with a mass splitting , interacting with the SM particles through the Higgs portal. We find…
Size of the Gribov region in curved spacetime
Marco de Cesare, Giampiero Esposito, Hossein Ghorbani
Recent work in the literature has argued that the joint effect of spacetime curvature and the Gribov ambiguity may introduce further modifications to the Green functions in the inf…
Gauge-Stringy Instantons in N=2 U(N) Gauge Theories
Hossein Ghorbani
Using D3/D(-1) brane set-up in type IIB string theory we introduce gauge-stringy instantons in N=2 U(N) supersymmetry theories with one matter multiplet in symmetric representation…
Kaon semi-leptonic form factor at zero momentum transfer in finite volume
Karim Ghorbani, Hossein Ghorbani
Using Chiral Perturbation Theory, we obtain the kaon semi-leptonic vector form factor in finite volume at a generic momentum transfer, , up to one loop order. At first we conf…
