Calculation of Higher Order Corrections to Drell-Yan Pair Production from some Higher Dimensional Operators

Abstract

The standard model of particle physics is able to explain the structure of the universe very successfully. It has been proven very effective in understanding the processes of elementary particles. But there are scenarios which lie beyond the scope of SM. This project considers LeptonQuark contact interaction in addition to the existing interaction in the SM. This project required learning QED and QCD as prerequisites for the later work which involved the analytical calculations of the differential cross-section including these LLQQ interactions which are parameterized in terms of six-dimensional operators. The project focused on appending these operators to the existing codes and comparing the output with the existing experimental data.
