COMPLETE INITIAL STATE RADIATION TO OFF-SHELL Z PAIR PRODUCTION IN ee ANNIHILATION
A cross-section calculation for the Standard Model reaction ee → (ZZ) → f1f̄1f2f̄2 including the effects of the finite Z width and initial state radiative corrections is presented. The angular phase space integrations are performed analytically, leaving the invariant masses for numerical integration. Semi-analytical and numerical results in the energy range √ s = 150 GeV to 1 TeV are reported.
متن کاملComplete Initial State QED Corrections to Off-Shell Gauge Boson Pair Production in e+e− Annihilation
We study Standard Model four-fermion production in e+e− annihilation at LEP2 energies and above using a semi-analytical approach. We derive the complete QED initial state corrections (ISR) to the reactions e+e− → (Z0Z0) → f1f̄1f2f̄2 and e+e− → (W+W−) → f̄u 1 fd 1 fu 2 f̄d 2 with f1 6= f2 and fi 6= e±, (−) νe . As compared to the well-known universal s-channel ISR, additional complexity arises due t...
متن کاملOff shell W pair production in e + e − annihilation : The CC 11 process
The various four-fermion production channels in e+e− annihilation are discussed and the CC11 process e+e− → f̄ 1 f 1 f 2 f̄ 2 , f 6=e, is studied in detail. The cross section dσ/ds1ds2, with s1, s2 being the invariant masses squared of the two fermion pairs, may be expressed by six generic functions. All but one may be found in the literature. The cross section, including initial state radiation ...
متن کاملOff-shell W-pair production — universal versus non-universal corrections
Electroweak radiative corrections to ee scattering processes typically amount to O(10%) at LEP energies. Their logarithmic increase with energy renders them even more important at future colliders. Although the bulk of these corrections is due to universal process-independent effects, the remaining non-universal corrections are nevertheless phenomenologically important. We describe the structur...
