Cosmological Constraints on Long-Lived Particles Using Dimension-Six Effective Operators
Mickael V. S. de Farias, Rodrigo Holanda, Matheus M. A. Paixao +2
Long-lived particles (LLPs) provide an interesting window into physics beyond the Standard Model, offering characteristic signatures at colliders and in cosmology. In this work, we…
Dark Matter as a Source for Lepton Flavor Violation
Jeremy Echeverria, Patricio Escalona, Farinaldo Queiroz +1
We will witness enormous progress in the experimental sensitivity to charged-lepton-violation processes in the near future. New physics signals of charged lepton violation might be…
Multi-Component Dark Matter as a Solution to the Galactic Center GeV Excess
Farinaldo S. Queiroz, Clarissa Siqueira, Carlos E. Yaguna
The Galactic Center Excess (GCE) is a compelling signature of dark matter annihilation, but its spectral morphology is difficult to reconcile with the traditional paradigm of a sin…
Latin American HECAP Physics Briefing Book 2025
Mario A. Acero, Alexis A. Aguilar-Arevalo, Belén Andrada +24
The first process for the Latin American Strategy Forum for Research Infrastructure for High Energy, Cosmology and Astroparticle Physics (LASF4RI-HECAP) came to a conclusion in Oct…
Updated Bounds on the Minimal Left-Right Symmetric Model from LHC Dilepton Resonance Searches
Gabriela Lichtenstein, Ricardo C. Silva, Mario J. Neves +1
The Left-Right model is a popular extension of the Standard Model that features three new neutral gauge bosons, and . Collider searches for a Left-Right symmetry a…
Search for Axions and Dark Photons Using Single Molecule Magnets
Jose R. Alves, Manfred Lindner, Farinaldo S. Queiroz +1
Molecular magnets, although analogous to familiar macroscopic magnets, offer a platform for next generation magnetic storage technologies with far higher data densities and prospec…
