Stochastic bias from loops of massive particles during inflation
Primordial non-Gaussianities enhanced at small wavevectors can induce a power spectrum of the galaxy overdensity that differs greatly from that of the matter overdensity at large length scales. In previous work, it was shown that “squeezed” three-point and “collapsed” four-point functions of the cur...
