Massive neutrinos and interacting dark matter look alike through the lens of lensing
Luis A. Anchordoqui, Danny Marfatia, Jorge F. Soriano
We demonstrate that the suppression in the lensing power spectrum of the cosmic microwave background (CMB) caused by massive neutrinos can be mimicked by dark matter-baryon interac…
Letter of Intent: The Forward Physics Facility
Luis A. Anchordoqui, John K. Anders, Akitaka Ariga +111
The Forward Physics Facility (FPF) is a proposed extension of the HL-LHC program designed to exploit the unique scientific opportunities offered by the intense flux of high energy…
Species Quantum Mechanics
Luis A. Anchordoqui, Dieter Lust, Severin Lüst
In this note we introduce some concepts of Species Quantum Mechanics. Specifically, we consider quantum operators that correspond to the species number and the tower mass sca…
Primordial Black Holes are 5D
Luis A. Anchordoqui, Alek Bedroya, Dieter Lüst
We revisit well-established mechanisms for primordial black hole (PBH) production, namely inflation, phase transitions, and cosmic strings, in the context of the Dark Dimension Sce…
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…
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}~{\rm…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
The Forward Physics Facility at the Large Hadron Collider
Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +21
The Forward Physics Facility (FPF) is a proposal developed to exploit the unique scientific potential made possible by the intense hadron beams produced in the far-forward directio…
S-dual Quintessence, the Swampland, and the DESI DR2 Results
Luis A. Anchordoqui, Ignatios Antoniadis, Dieter Lust
We propose a dark energy model in which a quintessence field rolls near the vicinity of a local maximum of its potential characterized by the simplest self-dual form $V(ϕ)…
Sombrero Galaxy as an Accelerator of Ultrahigh Energy Cosmic Ray Nuclei
Luis A. Anchordoqui, Karem Peñaló Castillo
Motivated by a recent proposal that points to the Sombrero galaxy as a source of the highest energy cosmic rays, we investigate the feasibility of accelerating light and heavy nucl…
New insights on a sign-switching
Jorge F. Soriano, Shimon Wohlberg, Luis A. Anchordoqui
The proposal for a sudden sign-switching cosmological constant in the local universe, emulating a phase transition from anti-de Sitter (AdS) to de Sitter (dS) space, has marked…
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…
