Evidence of the Exclusive Jet Production Using the ATLAS Detector

Discoveries in the domain of exact sciences should be described by a theory. In the case of High Energy Physics (HEP), the widely used one is the Standard Model (SM). Despite its undoubted success in explaining many phenomena, it is not a complete theory. For example, it does not explain/include gravitation, dark matter or neutrino masses. Nevertheless, the Standard Model works well to explain diffractive jet phenomena, which are a subject of this thesis. In this chapter, the Standard Model will be briefly described. The stress will be put on Quantum Chromodynamics (QCD) which is nowadays used to describe the diffractive physics processes
