Objetivo
The ultimate goal of any theory describing nature is to be able to predict, on the basis of few assumptions, the behaviour of its components. Quantum field theory has enjoyed great success in this respect. The quantity which describes the behaviour of the components of the theory is called scattering amplitude: it describes the effect of the interaction of a subset of the components of the system with the rest of it. This interaction depends crucially on a parameter of the theory, the coupling constant, whose magnitude may vary with the energy. The quantum field theory of our interest is the Standard Model of particle physics, the theory which describes the behaviour of protons, neutrons, quarks, photons, leptons and massive gauge bosons. The coupling constant of the theory is small for a wide range of energies. In this regime there is a very efficient computational tool, called perturbation theory, which have proved successful both at the theoretical level, allowing for many interesting computations, and at the experimental level where many of those computations have been measured. The opposite regime (large coupling constant) is called non-perturbative and very little is known about it mainly for the lack of computational tools to approach it. The aim of this project is to develop and use efficient mathematical tools to compute the relevant characteristics of a variant of the Standard Model, the Supersymmetric Standard Model a theory soon to be tested by the new European facility at CERN: the Large Hadron Collider (LHC). In order to do so we plan to hire a top-class researcher from a third country who is a founder and an expert in the field of non perturbative techniques, in which European groups are already world-leaders. This will strengthen the relationship between our laboratory and the host institution of the researcher to be hired which is already under way since we have already hired (for two years) a younger researcher from that institution.
