In this study, we investigate the potential of these colliders for a four-fermion contact interactions search. Regarding the con-structive and destructive interferences of contact interactions, we estimated discovery, observation, and exclusion limits on the compositeness scale for the left-left, right-right, left-right, and right-left helicity structures. In this regard, we obtained compositeness scales for the left-left helicity structure at root s = 63.2 TeV FCC-based mu p collider with the 100 fb-1 integrated lu-minosity as 225.7 +/- 1.9% TeV (discovery), 269.0 +/- 2.0% TeV (observation), and 311.3 +/- 2.1% TeV (exclusion). This study's findings show that the FCC-based mu p colliders have great potential for investigating four-fermion contact interactions.eninfo:eu-repo/semantics/openAccessDijet Angular-DistributionsFermion-Pair ProductionLarge Extra DimensionsPp CollisionsHadron CollidersLepton-HadronRoot-S=13 TevSearchQuarkModelArticle531112010.5506/APhysPolB.53.11-A32-s2.0-85148287313Q3WOS:000901943800001Q4
