title = "Angular distributions for high-mass jet pairs and a limit on the energy scale of compositeness for quarks from the CERN p{\=p} collider",

abstract = "Angular distributions of high-mass jet pairs (1802J<350 GeV) have been measured in the UA1 experiment at the CERN p{\=p} Collider ( s=630GeV). We show that angular distributions are independent of the subprocess centre-of-mass (CM) energy over this range, and use the data to put constraints on the definition of the Q2 scale. The distribution for the very high mass jet pairs (240 2J<300 GeV) has also been used to obtain a lower limit on the energy scale Λc of compositeness of quarks. We find Λc>415 GeV at 95% confidence level.",
