A tour to subatomic world through precision quantum chromodynamics

The quest for our understanding of the behaviour of the
fundamental constituents of matter has been going on for several centuries.
In describing the behaviour of all non-gravitational phenomena in our
Nature, the Standard Model (SM) of particle physics is so far the most
successful candidate. It is a theory based on the principles of quantum
mechanics. Despite its spectacular success, it is quite evident that it is
not complete - Nature exhibits phenomena that are not describable through
the SM. However, while there exist several indirect shreds of evidence, the
lack of direct evidence has led us to examine the SM with an eagle eye. This
exploration depends upon our ability to the development of innovative high
energy colliders and our capability to perform precise theoretical
calculations. In this colloquium, we will be acquainted with
state-of-the-art techniques to perform precision calculations in
perturbative quantum chromodynamics and its indispensable role in the
development of our understanding of the fundamental behaviour of Nature.
