Kaluza--Klein Dark-Photon Mediation of Inelastic Dark Matter at LUX-ZEPLIN
Waqas Ahmed, George K. Leontaris
We study a five-dimensional realization of endothermic dark matter motivated by the recent high-recoil LUX-ZEPLIN event. A pseudo-Dirac Standard-Model singlet fermion is localized…
A Dark-Dimension Origin of Geometric Inelastic Dark Matter: The LUX-ZEPLIN High-Recoil Event and Multi-Target Tests
Waqas Ahmed, George K. Leontaris
The extended nuclear-recoil analysis of LUX-ZEPLIN (LZ) has reported one event compatible with a recoil energy near keV, motivating endothermic dark-matter scenarios with sup…
Tetra-quadric CY Threefold and Assisted Fibre Inflation
Swagata Bhattacharyya, George K. Leontaris, Pramod Shukla
In the context of type IIB superstring compactification, we demonstrate the assisted fibre inflation proposal for a four-field model realized using the orientifold of a tetra-quadr…
Probing Two Dark Dimensions through Primordial Black Holes, Gravitational Waves, and Colliders
Waqas Ahmed, George K. Leontaris
We study primordial-black-hole (PBH) dark matter in the two-dark-dimensions (2DD) framework, a six-dimensional brane-world scenario with two compact extra dimensions and a fundamen…
Secondary Gravitational Wave Signatures from 5D Rotating Primordial Black Holes in the Dark Dimension
Waqas Ahmed, George K. Leontaris
We investigate five-dimensional rotating primordial black holes (PBHs) as dark matter candidates within the Dark Dimension (DD) scenario motivated by the Swampland Program. In this…
Micron-sized Extra Dimensions and Primordial Black Holes: Charged, Rotating, and Memory Burdened
George K. Leontaris, George Prampromis
We explore the possibility of explaining dark matter through six-dimensional (6D) primordial black holes (PBHs) in a theory with two extra dimensions. Interestingly, in this scenar…
