Geometric scaling as traveling waves.

We show the relevance of the nonlinear Fisher and Kolmogorov-Petrovsky-Piscounov (KPP) equation to the problem of high energy evolution of the QCD amplitudes. We explain how the traveling wave solutions of this equation are related to geometric scaling, a phenomenon observed in deep-inelastic scattering experiments. Geometric scaling is for the first time shown to result from an exact solution of nonlinear QCD evolution equations. Using general results on the KPP equation, we compute the velocity of the wave front, which gives the full high energy dependence of the saturation scale.

Inclusive Higgs Boson and dijet production via double Pomeron exchange.

We evaluate inclusive Higgs boson and dijet cross sections at the Fermilab Tevatron collider via double Pomeron exchange. Such inclusive processes, normalized to the observed dijet rate observed at Run I, noticeably increase the predictions for tagged (anti)protons in Run II with respect to exclusive production, with the potentiality of Higgs boson detection.

Unifying approach to hard diffraction.

We find a consistency between two different approaches of hard diffraction, namely, the QCD dipole model and the soft color interaction approach. A theoretical interpretation in terms of S-matrix and perturbative-QCD properties in the small x(Bj) regime is proposed.
