Bhabha Scattering at NNLO
We review the status of the calculation of next-to-next-to-leading order corrections to large angle Bhabha scattering in pure QED. After discussing the electron-loop and photonic corrections, we focus on the recently calculated two-loop virtual corrections involving a heavy-flavor fermion loop. We conclude by assessing the numerical impact of these corrections on the Bhabha scattering cross sec...
متن کاملHighlights from Muon Scattering at CERN
A review is given of recent results from the deep inelastic muon scattering program at CERN, focusing on high statistics measurements of scaling violations and tests of QCD, and on past and future experiments to measure the spin structure functions of the nucleon.
متن کاملOne-loop QCD corrections to quark scattering at NNLO∗
We present the O(α s) virtual QCD corrections to unlike-quark qq̄ → q q̄ and like-quark scattering qq̄ → qq̄ due to the interference of one-loop amplitudes with one-loop amplitudes. The structure of the infrared divergences agrees with that predicted by Catani. The results are expressed in an analytic form so that the relevant expressions for crossed scattering processes can be obtained in a straig...
متن کاملInequality for Electron and Muon Scattering from Nucleons
Equation (1) has the classic structure of a sum rule except for the factor of 2 mismatch. It occurs because half of the point cross section comes from the isoscalar current, about (3) E and E' are incident and final laboratory energies of the electron, 8 the scattering angle, and q'=4EE'sin'(8/2). o is the total (elastic + inelastic) electron-proton cross section and cr &S the cross-section fro...
