DESCRIPTION:Speakers: Simone Zoia (CERN)\n\n\n\nThe computation of multi-l
 oop scattering amplitudes remains a central bottleneck in achieving the th
 eoretical precision needed to fully exploit the increasingly accurate data
  from the Large Hadron Collider. The challenge is particularly daunting fo
 r processes involving many particles and masses\, which are nonetheless of
  great phenomenological interest for the LHC. The main difficulties arise 
 from the enormous size of the resulting algebraic expressions and from the
  appearance of special functions for which a practical mathematical framew
 ork is still lacking.In this seminar\, I will present recent progress towa
 rds overcoming these obstacles by combining novel analytic methods with nu
 merical techniques. I will illustrate these developments with applications
  to the computation of two-loop QCD amplitudes for key LHC processes: the 
 production of a top-antitop pair in association with either a jet or a W b
 oson.ZOOM LINK\n\n\n\nhttps://indico.global/event/17519/
