Abstract In this project we will study the 3 point correlation function of the density contrast field and its Fourier transform: the bispectrum. The bispectrum importance is due to the non-gaussianities. Non-gaussianities arise in the density field evolution, but they are also associated with inflation models. The 3PCF calculus has additional information if compared to the 2PCF. For its calculus, one alternative is using the perturbation theory loop corrections. Recently, it has been used the called effective field theory (EFT). We will calculate theoretically this terms and also compare with simulated catalogues and with the Dark Energy Survey data.
