10 Feb, Ivan Esteban: Long Range Interactions in Cosmology - Implications for Neutrinos

a talk by Ivan Esteban, Ohio State University

Cosmology is well suited to study the effects of long range interactions due to the large densities in the early Universe. In this talk, I will explore how the energy density and equation of state of a fermion system diverge from the commonly assumed ideal gas form under the presence of scalar long range interactions with a range much smaller than cosmological scales. In this scenario, "small"-scale physics can impact our largest-scale observations

As a benchmark, I will apply the formalism to self-interacting neutrinos, performing an analysis to present and future cosmological data. I will explore how this fully removes the cosmological neutrino mass bound, opening the possibility for a laboratory neutrino mass detection in the near future.I will also discuss an interesting complementarity between neutrino laboratory experiments and the future EUCLID survey.
