摘要

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 Q.
