Abstract
The paper combines galaxy data targeted with the Dark Energy Spectroscopic Instrument (DESI) with the associated galaxy lensing signal from the Year-3 Dark Energy Survey. The modeling implements novel effective and hybrid effective field theory aspects, independently confirming previous Cosmic Microwave Background results on the amplitude of the lensing signal, S8.
