An analytic description of the damping of gravitational waves by free streaming neutrinos

arXiv:1207.7285 · doi:10.1103/PhysRevD.88.083536

Abstract

We provide an analytic solution to the general wavelength integro-differential equation describing the damping of tensor modes of gravitational waves due to free streaming neutrinos in the early universe. Our result is expressed as a series of spherical Bessel functions whose coefficients are functions of the reduced wave number .
