Resonance Production of the Excited Quark at High Luminosity Large Hadron Collider

This study investigated the resonance production of excited quarks in the degenerate state using the interaction Lagrangian method. Calculations have been made for the signal channel in which the excited quarks produced in the resonance in High Luminosity Large Hadron Collider (HL-LHC) have dijet final states. Signal background analysis was performed to identify cuts to distinguish the excited quark signal from the background. Using the cuts determined by this analysis, the discovery, observation, and exclusion limits for the mass of the excited quark in the HL-LHC were calculated. In addition, a compositeness scale search was performed for the excited quark, and the highest compositeness scale values that it could reach for different mass values were calculated. Finally, it has been shown that the excited quark can be discovered in HL-LHC even with free parameter values less than 1. As a result of all these calculations, it has been revealed that HL-LHC will have an excellent potential in investigating excited quarks.
