Résumé:
In this master thesis, we tackle the problematic of pedagogically illuminating the link
between the theoretical framework of quantum field theory and actual experiments in
high energy physics (HEP) especially in the electroweak sector. To do that, we briefly
review the theoretical structure of the electroweak standard model theory and its quantized
Lagrangian, then revisit the ideas behind renormalization with applying the on-shell
renormalization scheme to the theory. Application to a leptonic process eν
was
made by the use of symbolic computation tools called FeynCalc[
26, 37], FeynArts and
FormCalc packages of Mathematica software.
