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…
Decoherence Effects on Primordial Black Holes and Scalar-Induced Gravitational Waves
Waqas Ahmed
Primordial black holes (PBHs) form when large primordial curvature perturbations re-enter the Hubble radius and exceed the classical collapse threshold. These perturbations origina…
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…
Entanglement, Discord, and Residual Coherence in Scalar-Induced Gravitational Waves
Waqas Ahmed
Scalar-induced gravitational waves (SIGWs) are usually characterized by their power spectrum, although their quadratic scalar source also carries higher-order correlation informati…
Quantum Memory in Scalar-Induced Gravitational Waves
Waqas Ahmed
Scalar-induced gravitational waves are usually treated as a classical stochastic background sourced by phase-random curvature perturbations. We show that this description can miss…
