Diffractive and Total pp Cross Sections at LHC

The single-diffractive and total pp cross sections at the LHC are predicted in a phenomenological approach that obeys all unitarity constraints. The approach is based on the renormalization model of diffraction and a saturated Froissart bound for the total cross section yielding t = ( /so) · ln2(s/sF ) for s > sF , where the parameters so and sF are experimentally determined from the ps-dependence of the single-diffractive cross section.
