Linear Dilaton in Cosmology and Particle Physics
Eugenio Megias, Mariano Quiros
A warped extra dimension in a five-dimensional (5D) anti-de Sitter (AdS) background was introduced in 1999 by Lisa Randall and Raman Sundrum to solve the gauge hierarchy problem in…
Massive Graviton Dark Matter from a Gapped Continuum
Eugenio Megias, Miguel Prieto, Mariano Quiros
We consider the possibility of dark matter in a warped extra-dimensional theory in the presence of a linear dilaton background, with a gapped continuum spectrum, in a brane-world c…
Stable Black Strings from Warped Backgrounds
Sylvain Fichet, Eugenio Megias, Mariano Quiros +1
We show that spacetime curvature alone can classically stabilize black strings. Working within a consistent five-dimensional dilaton-gravity system with a flat brane, we find that…
Holographic Dark Matter
Sylvain Fichet, Eugenio Megias, Mariano Quiros
Cold dark matter may be a fluid (or plasma) residing in a strongly-interacting hidden sector, rather than a population of weakly-coupled particles. Such a scenario admits a hologra…
Complementary Probes of Warped Extra Dimension: Colliders, Gravitational Waves and Primordial Black Holes from Phase Transitions
Anish Ghoshal, Eugenio Megias, Germano Nardini +1
We study the formation of primordial black holes (PBHs) and stochastic gravitational waves background (SGWB) produced by the supercooled radion phase transition (PT) in warped extr…
Entanglement Entropy and Thermal Phase Transitions from Curvature Singularities
Sergio Barbosa, Sylvain Fichet, Eugenio Megias +1
We study holographic entanglement entropy and revisit thermodynamics and confinement in the dilaton-gravity system. Our analysis focuses on a solvable class of backgrounds that inc…
Dark Branes for Dark Matter
Fotis Koutroulis, Eugenio Megias, Stefan Pokorski +1
We propose a setup for the origin of dark matter based on spacetime with a warped extra dimension and three branes: the Planck brane, the TeV brane, at a (few) TeV scale , and…
Drell-Yan Bounds on Gapped Continuum Spectra
Ernesto Arganda, Antonio Delgado, Adam Martin +4
Theories with gapped continuum spectra have gotten some attention, either as pure 4D models like unparticles, or in 5D realizations as certain soft walls constructions. In this pap…
Holographic Fluids from 5D Dilaton Gravity
Sylvain Fichet, Eugenio Megias, Mariano Quiros
We study a solvable class of five-dimensional dilaton gravity models that continuously interpolate between anti-de Sitter (AdS), linear dilaton (LD) and positively curved s…
Holography of Linear Dilaton Spacetimes from the Bottom Up
Sylvain Fichet, Eugenio Megias, Mariano Quiros
The linear dilaton background is the keystone of a string-derived holographic correspondence beyond AdS/CFT. This motivates an exploration of the -dimensional li…
Pulsar Timing Array Stochastic Background from light Kaluza-Klein resonances
Eugenio Megias, Germano Nardini, Mariano Quiros
We investigate the potential of the warped-extradimension framework as an explanation for the recently observed stochastic gravitational background at nHz frequencies in pulsar tim…
A light sneutrino rescues the light stop
Mikael Chala, Antonio Delgado, Germano Nardini +1
Stop searches in supersymmetric frameworks with -parity conservation usually assume the lightest neutralino to be the lightest supersymmetric particle. In this paper we consider…
