Polarized Structure Functions and Two-Photon Physics at Super-B
Abstract
The potential of polarized, 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 2-photon physics is proposed, focusing on measurements of the polarized photon structure functions g1 and g2 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 polarized photon structure function g1(x,Q^2;K^2) are described in detail. Cross-section formulae and experimental issues for investigations of NLO and higher-twist effects in g1 and g2 together with exclusive 2-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 signaling new physics beyond the standard model.
