| dc.description.abstract | We report on the first measurement of the angular distributions of final state electrons in p¯p???/Z?e+e?+X events produced in the Z boson mass region at ?s=1.96TeV. The data sample collected by the CDF II detector for this result corresponds to 2.1??fb?1 of integrated luminosity. The angular distributions are studied as a function of the transverse momentum of the electron-positron pair and show good agreement with the Lam-Tung relation, consistent with a spin-1 description of the gluon, and demonstrate that, at high values of the transverse momentum, Z bosons are produced via quark-antiquark annihilation and quark-gluon Compton processes. | es_ES |
