Neutrino Direct Simulation Monte Carlo: Accurate modeling of out-of-equilibrium decaying cosmological relics
Kensuke Akita, Miguel Escudero, Oleksii Ihnatenko +1
We consider nonstandard cosmologies in which decaying relics inject energy at MeV temperatures, driving neutrinos out of equilibrium. The subsequent neutrino evolution shapes predi…
What does it take to have at CMB times?
Miguel Escudero, Maksym Ovchynnikov, Neal Weiner
The vast majority of extensions of the Standard Model affecting the number of effective relativistic neutrino species () do so additively, namely, they enhance this qu…
A Limit on the Total Lepton Number in the Universe from BBN and the CMB
Valerie Domcke, Miguel Escudero, Mario Fernandez Navarro +1
At temperatures below the QCD phase transition, any substantial lepton number in the Universe can only be present within the neutrino sector. In this work, we systematically explor…
Lepton Flavor Asymmetries: from the early Universe to BBN
Valerie Domcke, Miguel Escudero, Mario Fernandez Navarro +1
Large primordial lepton flavor asymmetries with almost vanishing total baryon-minus-lepton number can evade the usual BBN and CMB constraints if neutrino oscillations lead to perfe…
Living at the Edge: A Critical Look at the Cosmological Neutrino Mass Bound
Daniel Naredo-Tuero, Miguel Escudero, Enrique Fernández-Martínez +2
Cosmological neutrino mass bounds are becoming increasingly stringent. The latest limit within CDM from Planck 2018+ACT lensing+DESI is at 95\% CL, v…
