Sterile Neutrino as an Asymmetric Dark Matter
S. Peyman Zakeri
We propose a minimal and predictive framework for asymmetric sterile neutrino dark matter (DM) produced via freeze-in. The standard model (SM) is extended by a gauge-singlet Dirac…
Searching for Vector-Like Quarks in a Fermionic Dark Matter Model with Pseudoscalar: A Resonance Case
Seyed Yaser Ayazi, Ahmad Mohamadnejad, S. Peyman Zakeri
We propose a minimal model of a fermionic dark matter with a pseudoscalar mediator and N generation of vector-like quarks. We calculate the relic density and obtain new constraint…
A Minimal Model For Two-Component FIMP Dark Matter: A Basic Search
S. Peyman Zakeri, S. Mohammad Moosavi Nejad, Mohammadreza Zakeri +1
In the multi-component configurations of dark matter phenomenology, we propose a minimal two-component configuration which is an extension of the Standard Model with only three new…
Non-monotonic Casimir interaction: The role of amplifying dielectrics
Morteza Soltani, Jalal Sarabadani, S. Peyman Zakeri
The normal and the lateral Casimir interactions between corrugated ideal metallic plates in the presence of an amplifying or an absorptive dielectric slab has been studied by the p…
Freeze-in production of Fermionic Dark Matter with Pseudo-scalar and Phenomenological Aspects
Seyed Yaser Ayazi, S. Mahdi Firouzabadi, S. Peyman Zakeri
In this paper, we study freeze-in production of fermionic dark matter with a pseudo scalar as the mediator between dark sector and Standard Model (SM). While the fermionic DM is no…
Biaccessiblility in quadratic Julia sets I: The locally-connected case
Saaed Zakeri
Let be a quadratic polynomial whose Julia set is locally-connected of the set of biaccessible points in is zero except when is the Chebyshev…
