Gravitational waves from scale-invariant vector dark matter model: Probing below the neutrino-floor
Ahmad Mohamadnejad
We study the gravitational waves (GWs) spectrum produced during the electroweak phase transition in a scale-invariant extension of the Standard Model (SM), enlarged by a dark $ U(1…
Accidental scale-invariant Majorana dark matter in leptoquark-Higgs portals
Ahmad Mohamadnejad
We study a classically accidental scale-invariant extension of the Standard Model (SM) containing three additional fields, a vector leptoquark (), a real scalar (), and…
Conformal vector dark matter and strongly first-order electroweak phase transition
Seyed Yaser Ayazi, Ahmad Mohamadnejad
We study a conformal version of the Standard Model (SM), which apart from SM sector, containing a dark sector with a vector dark matter candidate and a scalar field (s…
Scale-Invariant Two Component Dark Matter
Seyed Yaser Ayazi, Ahmad Mohamadnejad
We study a scale invariant extension of the standard model which can explain simultaneously dark matter and the hierarchy problem. In our set-up, we introduce a scalar and a spinor…
Cosmological evolution of the proton-to-electron mass ratio in an extended Brans-Dicke theory
Ahmad Mohamadnejad
We study variation of the proton-to-electron mass ratio by incorporating standard model (SM) of particle physics into an extended Brans-Dicke theory. We show that…
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…
