Angular distributions of high-mass dileptons in high-energy hadronic collisions
Journal Article

· Phys. Rev. D; (United States)
The angular distributions for dileptons arising from decays of a virtual photon and the Z/sup 0/ produced in hadronic collisions are calculated at large mass and finite transverse momentum of dileptons in the lowest order of quantum chromodynamics and the Weinberg-Salam model with three fermion generations. Numerical evaluation for coefficients of the distributions is carried out for p-barp collisions at ..sqrt..s = 540 GeV and pp at ..sqrt..s = 800 GeV in different (helicity, Gottfried-Jackson, and Collins-Soper) reference frames. Coefficients of parity-violating terms in the distributions exhibit clean signs of the Z/sup 0/ boson, while those of parity-conserving terms are quite insensitive to the presence of the Z/sup 0/ boson.
