Angular distributions for dileptons formed in hadronic collisions at large mass Q/sup 2/ and large transverse momentum Q/sub t/ 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 Q/sub t//sup 2/, the distributions scale in the variable w=Q/sub t/ /sup 2//Q/sup 2/, and thus are independent of total energy. (c) Each subprocess exhibits a characteristic function of w, independent of the constituent distributions.
