Higher order radiative corrections at LEP energies

The form factors of ωπ0 and π+π− at ψ(2S)

“…F (x, s) has been calculated to an accuracy of 0.1% [5,6,7] and Π(s) is the vacuum polarization factor. In the upper limit of the integration, √ s ′ is the experimentally required minimum invariant mass of the final particles.…”

Measurement of triple gauge-boson couplings at 172 GeV

“…The e ect of the transverse distribution of initial state radiation was estimated using the EXCALIBUR MC sample. The EXCALIBUR event generator has a di erent implementation of initial state radiation and generates collinear initial state radiation [23], in contrast to both KORALW and PYTHIA. The e ect on the couplings was below 20% of the statistical uncertainties in the combined ts, highest for W .…”

“…Thus, by comparing with the two calculations in Refs. [4,5] as we do here, we get a measure of the size of the mass corrections as well as cross checks on both our differential and our integrated results.…”

“…In Section 4, we compare these results with those in Refs. [4,5] while illustrating our results as they are used in the KK MC in Ref. [2].…”

“…Concerning Ref. [4], the entire result was given only for the case in which the photon angle variables are all integrated out; here, we give the fully differential results. With regard to Ref.…”
