The Halo Mass Function from Excursion Set Theory. III. Non-Gaussian Fluctuations
We compute the effect of primordial non-Gaussianity on the halo mass function, using excursion set theory. In the presence of non-Gaussianity the stochastic evolution of the smoothed density field, as a function of the smoothing scale, is non-markovian and beside "local" terms that general...
