I present the analysis of the Dark Energy Survey 3x2pt data using predictions from the Effective Field Theory of Large-Scale Structure.

Using the one-loop expressions for the projected angular correlation functions, we validate our pipeline against numerical simulations and check for several internal consistencies before applying it to the observational data.

Fixing the spectral tilt and the baryons abundance, we measure S8 = 0.833 ± 0.032, Ωm = 0.272 ± 0.022, and h = 0.773 ± 0.049 at 68% CL.
