Constraining The Neutrino-Nucleon Cross Section with the Ultrahigh-Energy KM3NeT Event
Toni Bertólez-Martínez, Dan Hooper
KM3NeT's detection of a muon track produced by a neutrino provides an opportunity to probe physics at center-of-momentum energies greater than those probed…

Seafloor Topography Enhances KM3NeT Sensitivity to ANITA-like Events
Carlos A. Argüelles, Toni Bertólez-Martínez, Alba Burgos-Mondéjar +3
In this article, we introduce the concept of topographic enhancement in the context of ultra-high-energy neutrino detection by underwater neutrino telescopes. We demonstrate that t…

BBN bounds on neutrinophilic ultralight Dark Matter
Toni Bertólez-Martínez, Justo López-Sarrión, Jordi Salvado
The high densities in the early Universe provide a unique laboratory to constrain couplings between feebly interacting particles, such as dark matter and neutrinos. In this article…
