Integrated Perturbation Theory and One-loop Power Spectra of Biased
  Tracers
  General and explicit predictions from the integrated perturbation theory
(iPT) for power spectra and correlation functions of biased tracers are derived
and presented in the one-loop approximation. The iPT is a general framework of
the nonlinear perturbation theory of cosmological density fields in presence of
nonlocal bias, redshift-space distortions, and primordial non-Gaussianity.
Analytic formulas of auto and cross power spectra of nonlocally biased tracers
in both real and redshift spaces are derived and the results are
comprehensively summarized. The main difference from previous formulas derived
by the present author is to include effects of generally nonlocal Lagrangian
bias and primordial non-Gaussianity, and the derivation method of the new
formula is fundamentally different from the previous one. Relations to recent
work on improved methods of nonlinear perturbation theory in literature are
clarified and discussed.
