Limitations of Freeze-in WIMP Dark Matter from Supercooled Phase Transitions
Seyed Yaser Ayazi, Mojtaba Hosseini
We revisit the possibility of producing Weakly Interacting Massive Particle (WIMP) dark matter via a freeze-in mechanism triggered by a supercooled first-order phase transition (FO…
Gravitational wave signatures of first-order phase transition in two-component dark matter model
Seyed Yaser Ayazi, Mojtaba Hosseini, Rouzbeh Rouzbehi
Here, we consider a classically scale-invariant extension of the Standard Model (SM) with two-component dark matter (DM) candidates, including a Dirac spinor and a scalar DM. We pr…
Gravitational wave in a filtered vector dark matter model
Mojtaba Hosseini, Seyed Yaser Ayazi, Ahmad Mohamadnejad
We consider a first order phase transition (FOPT) for a Vector Dark Matter (VDM) in the early universe in which its mass may partially arise from such mechanism in the hidden secto…
Vector dark matter and LHC constraints, including a 95 GeV light Higgs boson
Seyed Yaser Ayazi, Mojtaba Hosseini, Saeid Paktinat Mehdiabadi +1
We study LHC searches for an extension of the Standard Model (SM) by exploiting an additional Abelian gauge symmetry and a complex scalar Higgs portal. As the scalar is ch…
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…
