Threshold Effects of Diffractive Production

It is proved in a quite general Feynman diagram model that the presence of diffractively produced inelastic channels at high energies leads to a decrease in the total cross section below as well as above the threshold for the process. A nondiffractive channel is shown to lead to the opposite effect, namely, the total cross section is increased at large energies. Asymptotically, the former behav...

- Production in Diffractive DIS

We calculate the cross section for q ¯ qg-production in diffractive DIS with finite fermion masses and zero momentum transfer. The calculation is done in the leading log(1/x P) approximation and is valid for the region of high diffractive masses (small β). We apply our cross section formula to diffractive charm production at HERA: in a Monte-Carlo-Simulation of diffractive D * ± meson productio...

Diffractive Higgs production

Instrumenting the LHC to measure the outgoing protons in the process pp → p+X + p opens up new possibilities for physics studies in the Standard Model and beyond. In this talk I first present an overview of the underlying QCD calculation and its uncertainties. I then move on to present a variety of new physics scenarios which one would want to explore via this unique channel. There is a short d...

Diffractive Higgs production: theory

We review the calculation for Higgs production via the exclusive reaction pp → p + H + p. In the first part we review in some detail the calculation of the Durham group and emphasise the main areas of uncertainty. Afterwards, we comment upon other calculations.

Results on Hard Diffractive Production

The results of experiments at hadron colliders probing the structure of the pomeron through hard diffraction are reviewed. Some results on deep inelastic diffractive scattering obtained at HERA are also discussed and placed in perspective. By using a properly normalized pomeron flux factor in single diffraction dissociation, as dictated by unitarity, the pomeron emerges as a combination of vale...
