The Impossible Triangle: A No-Go for Symmetry-Protected Scalar Portals in Interacting Dark Energy
Mohid Farhan
The tension motivates interacting dark energy (IDE), but embedding IDE in UV-complete physics faces severe naturalness challenges. We analyze four symmetry-protected DM--DE p…
Dark Matter and Dark Energy in Three-Higgs Doublet Model
Mohid Farhan, Ibtehaj Hassan, Muhammad Usman +1
This article discusses the incorporation of dark matter and dark energy into a new physics model called the Three-Higgs Doublet Model. Dark matter and dark energy are accommodated…
Layered dark structure with a Structuring Field: A -symmetric Inert Doublet-Singlet realization and implications for the tension
Marriam Naeem, Mohid Farhan
We introduce the Layered Dark Sectors with a Structuring Field (LDS-SF), a structured cosmological framework where the internal architecture of a multi-component dark sector natura…
Symmetry-Protected Momentum Exchange between Dark Matter and Dark Energy
Mohid Farhan
We present a particle physics motivated realization of interacting dark energy in which a radiatively stable dark energy sector couples to weakly interacting massive particle dark…
Relic Density Topology as a Discriminatory Tool: A Comparative Analysis of IDM, MSSM, and NMSSM Dark Matter
Mohid Farhan
This study proposes a diagnostic mechanism based on the relic density topology to discriminate between the Inert Doublet Model (IDM), the Minimal Supersymmetric Standard Model (MSS…
