"Deriving the scale-dependent bias from the integrated perturbation theory"
The scale-dependent bias in the large-scale structure is a promising probe for the primordial non-Gaussianity. An analytic formula of the scale-dependent bias is derived in the framework of integrated perturbation theory with an arbitrary primordial bispectrum. Approximations such as the peak-background split, the high-peak limit, or the local bias models are not required in this derivation. The previous formulas with above approximations are re-derived as limiting cases of the general formula. We show that the nonlocal nature of the halo bias is important to quantitatively understand the scale-dependent bias from the primordial non-Gaussianity. Redshift-space distortions of the scale-dependent bias are also investigated.
