    Description
  • Part I: discussion of recent papers/events
  • Part II: Talk by Pierpaolo Mastrolia
    • Abstract: I discuss how complex analysis can be employed for computing one-loop scattering amplitude very efficiently. I would like to show how spinorial-variables and Cauchy residues theorem are suitable for the analytic integration of cut-integrals; whereas the Discrete Fourier Transform optimizes the integrand-reduction (a' la OPP), in semi-numerical calculation.
