Main Scientific achievements. The framework of my research work is mostly on strong interaction sin high energy collisions, As is well known, strong interaction always represent a challenge to our ability to make predictions in high energy collisions, for the several reasons. First of all, the strong coupling constant is typically the largest one in the Standard Model. It is often needed to go beyond the leading perturbative order, and, at times, to resum kinematically enhanced contributions in order to have a reasonable assessment of cross sections and distributions. As a further point, the low energy(long distance) regime of QCD is not calculable, It is necessary to separate the short distance and long distance regime of QCD, where the former can be computed in a sound way, and the latter must rely upon modeling, in order to give an exclusive description of strong interaction final states in high energy collisions.
Today we have reliable methods to compute cross sections for high energy processes, The great success of the LHC physics program relies heavily upon these methods, Higgs production itself, and the determination of the Higgs couplings in the Standard Model relies upon calculations of strong processes, that involve perturbative calculations to the level of two-loop accuracy, resummation of all order contributions enhanced in the partonic threshold region, and simulation of the full events carried out by combining perturbative calculations, Shower Monte Carlo algorithms and models of the long distance physics leading to the formation of hadrons.I list below few topics in my scientific career where I have obtained groundbreaking results that had considerable subsequent development in this framework.
