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…

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…

On the phenomenological implications of a Pati-Salam model spontaneously broken by Higgs fields in fundamental representations

George K. Leontaris, Ruiwen Ouyang, Ye-ling Zhou

We present a supersymmetric Pati-Salam model with small representations as a potential candidate for physics beyond the Standard Model. The model features a Higgs sector with bifun…

Modular Family Symmetry in Fluxed GUTs

Vasileios Basiouris, Miguel Crispim Romão, Stephen F. King +1

We discuss modular family symmetry in effective theories based on generic properties of bottom-up local F-theory inspired GUTs broken by fluxes, which we refer to as Fluxed GUTs. W…
