Translated title:
Modern techniques in scattering amplitudes calculations
Summary:
This Master Thesis is divided into two parts. In the first part we introduce
all new efficient methods for calculating Scattering Amplitudes. We present
spinor products and color ordering. Formal aspects of Scattering Amplitudes
such as identities that they respect are discussed. We move the discussion to
the complex plane in order to construct the BCFW recursion relation. We analyze
the large z behavior of the Scattering Amplitudes. We discuss Scattering
Amplitudes for N=4 Super Yang Mills theory and the supersymmetric version
ofBCFW recursion. In the second part we calculate all tree level amplitudes of
N=4 Super Yang Mills Theory. Finally we give some insights on modern techniques
for loop calculations and more fancy aspects of field theory such as the
relation between Wilson loops and scattering amplitudes and the all loop
integrant for N=4 Super Yang Mills theory.
Keywords:
Field Theory, Scattering Amplitudes, Supersymmetry, Yang- Mills, Twistors
