Abstract: "The remarkable development of particle physics is based on gauge theory. The theory of simple electrodynamical gauge interactions laid the foundation for non-abelian gauge theories like Quantum Chromo Dynamics (QCD). At high energies, the QCD particles or the coloured particles are asymptotically free. However, at low energies, these coloured particles can not remain free. At a high energy collider, such as at the Large Hadron Collider, free coloured particles may be produced. They tend to shower and hadronize as they travel before hitting a detector. As a result, they are not detected freely, rather, they are detected as a collimated bunch of particles at the detector. The study of these collimated bunches of hadrons, called jets, provides important information about the interactions. The understanding of jets is state-of-the-art research in today's collider studies. In this talk, I will try to give an overview of the study of jets at a collider."
