Speaker: Vsevolod Chestnov (Istituto Nazionale di Fisica Nucleare) The percent-level precision achieved by experiments at the LargeHadron Collider demands theoretical predictions of comparable accuracy, necessitating higher-order perturbative corrections to scattering amplitudes. Traditionally, these corrections are computed by reducing the Feynman integralexpansion of an amplitude to a finite basis of linearly independent elements, followed by numerical …
