IR Black Hole Instabilities Trigger Species-Scale Particle Production
Luis A. Anchordoqui, Alek Bedroya, Dieter Lüst +1
We propose a novel UV-IR mechanism in quantum gravity in which black hole instabilities act as a bridge to the most ultraviolet sector of the theory. Specifically, we argue that wh…
Neutrinos from Primordial Black Holes in Theories with Extra Dimensions
Luis A. Anchordoqui, Francis Halzen, Dieter Lust
The quantum gravity scale within the dark dimension scenario () roughly coincides with the energy scale of the KM3-230213A neutrino ($E_ν\sim 10^{8}~{\r…
Bulk/boundary Modular Quintessence and DESI
Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +4
The latest DESI DR2 results, when combined with other independent cosmological data on the Cosmic Microwave Background and supernovas, suggest a preference for dynamical dark energ…
Two Micron-Size Dark Dimensions
Luis Anchordoqui, Ignatios Antoniadis, Dieter Lust
Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In our paper we examine various observational bounds in scenarios w…
SUSY at the FPF
Luis A. Anchordoqui, Ignatios Antoniadis, Karim Benakli +2
Experimental searches for supersymmetry (SUSY) are entering a new era. The failure to observe signals of sparticle production at the Large Hadron Collider (LHC) has eroded the cent…
Cosmological Constraints on Dark Neutrino Towers
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust +1
We reexamine a dynamical dark matter model with Kaluza-Klein (KK) towers of gravitons and neutrinos fitting together in the dark dimension. We show that even though gravitational d…
