In this contribution, we compute the total cross section for proton-proton collisions at the Large Hadron Collider in the context of quantum chromo dynamics (QCD) parton saturation models presenting geometric scaling phenomenon. Moreover, prediction for pion-proton total cross section is also provided for asymptotic energies. The main theoretical uncertainties associated to the calculations are discussed.
