Forward-backward asymmetries in hadronically produced lepton pairs

It has now become possible to observe appreciable numbers of hadronically produced lepton pairs in mass ranges where the contributions of the photon and Z0 are comparable. Consequently, in the reaction p bar p→l-l++···, substantial forward-backward asymmetries can be seen. These asymmetries provide a test of the electroweak theory in a new regime of energies, and can serve as diagnostics for any new neutral vector bosons coupling both to quarks and to charged lepton pairs. copyright 1996 The American Physical Society
