Interference of QCD and weak interactions and the detection of vector bosons by hadronic jets: pp and anti pp collisions with polarized and unpolarized beams

Two-jet and single-jet cross sections and spin asymmetries are studied in polarized and unpolarized proton-proton and antiproton-proton collisions at collider energies √s = 200 to 1000 GeV. It is found that the interference terms between strong (QCD) and weak interactions strongly influence the parity violating weak cross section; especially, the vector boson peaks in pp cross-sections and parity violating asymmetries are masked almost completely at the lower part of the energy range considered. In anti pp collisions the vector boson peaks survive and a measurement of parity-violating asymmetries of double- and single-jet cross sections should lead to clear signals of the vector bosons.
