Description
I will present a new firsrt principle approach for higher order perturbation theory for massive neutrinos in large scale structure. The approach is based on a non-linear generalization of Gilbert's equation.
Combined with standard perturbation theory, it allows to calculate N-point statistics of density perturbations in mixed cold+hot dark matter cosmologies.
I apply the theory to compute the leading order bispectrum and use it as benchmark to test the validity of some simple approximations schemes.
