Forecasts show that line-of-sight dependent 3PCF tightens sigma_8 constraints by a factor of 5 over 2PCF alone for Roman ELG and DESI LRG samples on scales <80 Mpc/h using AbacusSummit simulations.
FolpsD combines EFT power spectrum and tree-level bispectrum with damping to enable joint analyses that improve cosmological constraints from DESI-like galaxy mocks by up to 30% on As and omega_cdm while extending the usable k-range without significant biases for LRG samples.

FolpsD: combining EFT and phenomenological approaches for joint power spectrum and bispectrum analyses
