Probing the neutrino chemical potential with cosmological observations
Pietro Ghedini, Riccardo Impavido, Stefano Gariazzo +2
The electron neutrino degeneracy parameter, , is tightly constrained by Big Bang Nucleosynthesis (BBN), while the degeneracy parameters of…
Are Cosmological Data Excluding Sterile Neutrinos or Only the Fully Thermalized Limit?
Artur Ladeira, Rafael C. Nunes, Eleonora Di Valentino +1
We present a cosmological reassessment of light sterile-neutrino scenarios, examining whether current observations exclude sterile neutrinos as a class or primarily constrain the f…
Towards Low-Energy Electron High-Resolution Spectroscopy with Transition-Edge Sensors
R. Ammendola, A. Apponi, G. Benato +62
We present a study of the energy resolution of transition-edge sensors (TESs) for the detection of electrons in the 100~eV kinetic energy range. The TES is a Ti-Au bilayer with an…
Impact of non-standard neutrino-electron interactions on Big Bang Nucleosynthesis
Julien Froustey, Stefano Gariazzo, Jaume Moncho +2
Neutrino non-standard interactions (NSI) with electrons, predicted in many extended theoretical models of particle physics, are known to alter the picture of neutrino decoupling fr…
Early-universe constraints on the electron mass
Michela Garramone, Stefano Gariazzo, Nicolao Fornengo
We investigate the impact of a nonstandard electron mass on early-Universe thermal history, focusing on neutrino decoupling and Big Bang Nucleosynthesis (BBN). In the standar…
