Deeply Virtual Compton Scattering: How to Test Handbag Dominance?
M. Diehl, T. Gousset, B. Pire +1
We propose detailed tests of the handbag approximation in exclusive deeply virtual Compton scattering. Those tests make no use of any prejudice about parton correlations in the pro…
Photon polarisation in diffractive deep inelastic scattering
M. Diehl
The distribution of a suitably defined azimuthal angle in diffractive deep inelastic scattering contains information on the polarisation of the exchanged photon. In particular it a…
Theory of elastic vector meson production: some recent developments
M. Diehl
I review some recent developments in the QCD description of elastic vector meson production, focusing on issues like the meson wave function, the gluon density in the proton, facto…
Testing the handbag contribution to exclusive virtual Compton scattering
M. Diehl, T. Gousset, B. Pire +1
We discuss the handbag approximation to exclusive deep virtual Compton scattering. After defining the kinematical region where this approximation can be valid, we propose tests for…
Physics with e^+e^- Linear Colliders
E. Accomando
We describe the physics potential of linear colliders in this report. These machines are planned to operate in the first phase at a center-of --mass energy of 500 GeV, bef…
Anomalous triple gauge couplings in e+ e- -> W+ W- and "optimal" strategies for their measurement
M. Diehl, O. Nachtmann
We show how one can measure anomalous WWZ- and WWgamma-couplings with minimal statistical error using integrated observables, without having to assume that the anomalous couplings…
