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…
Updated BBN Bounds on Hadronic Injection in the Early Universe: The Gravitino Problem
Lucia Angel, Giorgio Arcadi, Matheus M. A. Paixão +1
Late-decaying particles naturally arise in many extensions of the Standard Model, directly impacting key cosmological processes in the early universe, such as Big Bang Nucleosynthe…
The Hubble Tension: Relativistic Dark Matter Production from Long-lived Particles
Alvaro S. de Jesus, Matheus M. A. Paixão, Dêivid R. da Silva +2
The tension between direct measurements of the Hubble constant and those stemming from Cosmic Microwave Background probes has triggered a multitude of studies. The connection betwe…
