Abstract

The potential of polarised, high-luminosity, moderate-energy e ⁺ e ⁻ colliders for performing unique measurements in fundamental QCD is described, with particular reference to the proposed Super-B facility. An extensive programme of two-photon physics is proposed, focusing on measurements of the polarised photon structure functions and and pseudoscalar meson transition functions. The experimental requirements for Super-B to make the first measurement of the first moment sum rule for the off-shell polarised photon structure function are described in detail. Cross-section formulae and experimental issues for investigations of NLO and higher-twist effects in and together with exclusive two-photon meson production are presented. This programme of QCD studies complements the core mission of Super-B as a high-luminosity B factory investigating flavour physics and rare processes signalling new physics beyond the standard model.
