TESTS FOR 2-BODY QUANTUM-CHROMODYNAMIC SUB-PROCESSES IN DILEPTON ANGULAR-CORRELATIONS

Angular distributions for dileptons formed in hadronic collisions at large mass Q2 and large transverse momentum Qt are calculated, assuming various two-body quantum chromodynamic subprocesses. The main results are the following: (a) The polar and azimuthal distributions are correlated. (b) For fixed Qt2, the distributions scale in the variable w=Qt2Q2, and thus are independent of total energy. (c) Each subprocess exhibits a characteristic function of w, independent of the constituent distributions. © 1979 The American Physical Society.
