Abstract

This plan of activities includes some lines of investigation aimed at studying amplitudesscattering in several cases of interest. More specifically, this plan has as general objectives thestudy of scattering amplitudes in gauge and gravitation theories, seeking to concentratein the calculation of classical observables, as well as the analysis of inflationary correlators andunitarity in cosmology from the point of view of the cosmological bootstrap.
