Inflationary Particle Production and the Swampland
Dieter Lüst, Joaquin Masias, Mauro Pieroni +1
We investigate the impact of particle production during inflation in scenarios where an infinite tower of states features a mass scale that decreases exponentially along the inflat…
Supersymmetry, Large Extra Dimensions and the Gravitino Conjecture
Leonardo Bersigotti, Dieter Lust, Marco Scalisi
We investigate whether the absence of experimental signals for supersymmetry and extra dimensions can be understood as a correlated phenomenon. Assuming the Gravitino Conjecture, w…
Quintessential -attractors fit DESI
Alessandro Borys, Joaquin Masias, Marco Scalisi
We study quintessence in -attractor models in light of recent DESI indications for dynamical dark energy. We show that the \emph{knee} of the attractor potential provides an ex…
The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
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…
On the Origin of Species Thermodynamics and the Black Hole - Tower Correspondence
Alvaro Herráez, Dieter Lüst, Joaquin Masias +1
Species thermodynamics has been proposed in analogy to black hole thermodynamics. The entropy scales like an area and is given by the mere counting of the number of the species. In…
