London-like tensor modes of gravitational waves in cosmic string cosmology
Claudio Aravena-Plaza, Víctor Muñoz, Felipe A. Asenjo
From a classical analysis, we show that gravitational waves in a cosmological medium with equation of state can follow a London-like equation, implying that some gravitati…
Hadrophilic Light Dark Matter from the Atmosphere
Carlos A. Argüelles, Víctor Muñoz, Ian M. Shoemaker +1
Light sub-GeV dark matter (DM) constitutes an underexplored target, beyond the optimized sensitivity of typical direct DM detection experiments. We comprehensively investigate hadr…
Existence of Korteweg-de Vries Solitons and Relevance of Relativistic Effects in a Dusty Electron-Ion Plasma
Maricarmen A. Winkler, Víctor Muñoz, Felipe A. Asenjo
Nonlinear effects in the propagation of perturbations in a dusty electron-ion plasma is studied, considering fully relativistic wave motion. A multifluid model is considered for th…
Searching for light long-lived neutralinos at Super-Kamiokande
Pablo Candia, Giovanna Cottin, Andrés Méndez +1
Light neutralinos could be copiously produced from the decays of mesons generated in cosmic-ray air showers. These neutralinos can be long-lived particles in the context of R-parit…
Millicharged Particles from the Heavens: Single- and Multiple-Scattering Signatures
Carlos A. Argüelles, Kevin J. Kelly, Víctor M. Muñoz
For nearly a century, studying cosmic-ray air showers has driven progress in our understanding of elementary particle physics. In this work, we revisit the production of millicharg…
Exploring the Origin of Supermassive Black Holes with Coherent Neutrino Scattering
Victor Munoz, Volodymyr Takhistov, Samuel J. Witte +1
Collapsing supermassive stars () at high redshifts can naturally provide seeds and explain the origin of the supermassive black holes observed in…
New constraints on Heavy Neutral Leptons from Super-Kamiokande data
Pilar Coloma, Pilar Hernández, Víctor Muñoz +1
Heavy neutral leptons are predicted in many extensions of the Standard Model with massive neutrinos. If kinematically accessible, they can be copiously produced from kaon and pion…
Searches for Atmospheric Long-Lived Particles
Carlos Argüelles, Pilar Coloma, Pilar Hernández +1
Long-lived particles are predicted in extensions of the Standard Model that involve relatively light but very weakly interacting sectors. In this paper we consider the possibility…
