Studies of Diffractive Jet-Gap-Jet Events using $sqrt(s) = 13.6 TeV$ ATLAS Data

Diffraction was always an important part of the studies performed in the particle physics experiments. This is also true in the LHC era. Both theoreticians and experimentalists work on various aspects of diffractive measurements. For example, during the last 10 years, around 70 publications containing the words ‘diffraction’ and ‘LHC’ were posted yearly on arXiv. Unfortunately, despite many studies, this field still has many mysteries. Clearly, there is a strong need and place for input from the LHC data.
This work is devoted to one aspect of diffractive physics: the production of jets with a rapidity gap1 between them. Such events, called jet-gap-jet, should allow interesting tests of theoretical predictions. Moreover, the jet-gap-jet topology produced in the single diffractive and the double Pomeron exchange processes is poorly known – the latter was never measured experimentally. However, before going into the details of the analysis, a brief introduction to the theory and phenomenology of the process should be given.
