+ | <hidden TTP02-03 The radiative return at small angles: virtual corrections > Virtual corrections for electron--positron annihilation into | ||

+ | one real and one off-shell photon of invariant mass $Q^2$ are evaluated. | ||

+ | Special attention is paid to those configurations where the real photon | ||

+ | is collinear with the beam direction. This calculation is an important | ||

+ | ingredient of a Monte Carlo program, which simulates events with tagged | ||

+ | photons from initial-state radiation, including NLO corrections. | ||
