In this thesis we study the spinor helicity formalism (SHF). This formalism is essentially
based on Weyl spinors, where we write the physical quantities appearing in scattering amplitudes
in terms of these spinors. Here we study two distinct cases: massless particles and
massive ones and build the formalism for each case. After that, we apply SHF to study a few
scattering processes including different sides of techniques necessary to acquire.
We will also plot Feynman diagrams for scattering processes via the FeynArts package;
illustrate how the amplitudes for these processes are obtained by using the FeynCalc package
and showcase the SpinorsExtras package(sub-package of S@M) via a simple example to
obtain the amplitudes in terms of spinor products.
Key Words: Spinor Helicity Formalism, Tree Level Amplitude, Scattering Amplitude. |
