Abstract
Dissipative effects during neutrino decoupling in the early universe create a small backreaction on the Hubble rate, and lead to a small rise in tempe rature and entropy. We use a simplified thermo-hydrodynamic model, which pr ovides a causal approximation to kinetic theory, in order to estimate the b ackreaction effects and the entropy production.
