DESCRIPTION:The University of Valencia\, in collaboration with IFIC\, orga
nizes this Master and PhD course which will be given by William J. Torres
Bobadilla\, IFIC (UV-CSIC).\n\nContents of the course: \n\n\n Computation
al techniques for scattering amplitudes: QCD scattering amplitudes\, colou
r-ordered amplitudes\, spinor-helicity formalism\, momentum twistor variab
les.\n On-shell methods: Britto-Cachazo-Feng-Witten recursive relation\, m
ethods based on the unitarity and analyticity of the Scattering matrix\, g
eneralised unitarity\, quadruple cut.\n Feynman integrals: Passarino-Veltm
an reduction\, master integrals\, integration-by-parts-identities differen
tial equations for master integrals.\n Integrand reduction methods for mul
ti-loop scattering amplitudes: Ossola-Papadopoulos-Pittau method\, polynom
ial division module Groebner basis\, adaptive integrand decomposition.\n\n
\nThe calculation of scattering amplitudes has been playing a very importa
nt role in the physics of the LHC\, where more accuracy is required to com
pare our theoretical predictions with the experiments. In this course\, I
plan to focus on modern techniques for the perturbatively calculation of t
ree and multi-loop level amplitudes. In particular\, the latter are part o
f the main ingredients to perform a Next-to-Next-to-Leading order (NNLO) c
omputation\, which currently is the main target in the physics community.\
