We update Halo Zeldovich Perturbation Theory (HZPT), an analytic model forthe two-point statistics of dark matter, to describe halo and galaxyclustering, and galaxy-matter cross-correlation on nonlinear scales. The modelcorrecting Zeldovich has an analytic Fourier transform, and therefore is validin both configuration space and Fourier space. The model is accurate at the$2\%$-level or less for $P_{mm}$ (k < 1 h/Mpc), $P_{hm}$ (k < 1 h/Mpc),$P_{hh}$ (k < 2 h/Mpc), $P_{gm}$ (k < 1 h/Mpc), $P_{gg}$ (k < 1 h/Mpc),$\xi_{mm}$ (r > 1 Mpc/h), $\xi_{hm}$ (r > 2 Mpc/h), $\xi_{hh}$ (r > 2 Mpc/h),$\xi_{gm}$ (r > 1 Mpc/h), $\xi_{gg}$ (r > 2 Mpc/h), for LRG-like mock galaxies.We show that the HZPT model for matter correlators can account for the effectsof a wide range of baryonic feedback models and provide extended dark mattermodels which are of $1\% ~(3\%)$ accuracy for k < 10 (8) h/Mpc. We explicitlymodel the non-perturbative features of halo exclusion for the halo-halo andgalaxy-galaxy correlators, as well as the presence of satellites forgalaxy-matter and galaxy-galaxy correlation functions. We perform densityestimation using N-body simulations and a wide range of HOD galaxy mocks toobtain correlations of model parameters with the cosmological parameters$\Omega_{m}$ and $\sigma_{8}$. HZPT can provide a fast, interpretable, andanalytic model for combined-probe analyses of redshift surveys using scaleswell into the non-linear regime.
