Searches for QCD Instantons with ALFA Detector - Theory and Data

This work explores quantum chromodynamics (QCD) instantons, focusing on their potential experimental detection at the LHC. Instantons represent non-perturbative phenomena, enabling tunnelling transitions between QCD vacua. Motivated by the study of Khoze et al., we reevaluate his results and try to gain a better understanding. The valley approximation is applied to simplify theoretical calculations, aiming to enhance our understanding of instanton-induced processes and their observability.
