19 Sep 2003 | | Journal: | Phys.Rev. D69 (2004) 034012 | | Subject: | hep-ph | | Affiliation: | Lisbon U., CFTC), B.I. Ermolaev (Lisbon U., CFTC & Ioffe Phys. Tech. Inst.), M. Greco (Rome U., III & INFN, Rome), S.M. Oliveira (Lisbon U., CFTC), S.I. Troyan (St. Petersburg, INP | | Abstract: | The non-radiative scattering amplitudes for electron-positron annihilation into quark and lepton pairs in the TeV energy range are calculated in the double-logarithmic approximation. The expressions for the amplitudes are obtained using infrared evolution equations with different cut-offs for virtual photons and for W and Z bosons, and compared with previous results obtained with an universal cut-off. | | Source: | arXiv, hep-ph/0309230 | | Services: | Forum | Review | PDF | Favorites | |
