Diffraction Association and Flavoring of Pomeron
نویسنده
چکیده
The most important consequence of Pomeron being a pole is the factorization property. However, due to Pomeron intercept being greater than 1, the extrapolated single diffraction dissociation cross section based on a classical triple-Pomeron formula is too large leading to a potential unitarity violation at Tevatron energies. It is our desire here to point out that the “flavoring” of Pomeron plays the dominant role in resolving this apparent “paradox”. Talk presented at LAFEX Workshop on Diffractive Scattering (LISHEP98), Rio de Janeiro, Brasil, Feb. (1998).

Diffractive Production at Collider Energies and Factorization
The most important consequence of Pomeron being a pole is the factorization property. However, due to Pomeron intercept being greater than 1, the extrapolated single diffraction dissociation cross section based on a classical triple-Pomeron formula is too large leading to a potential unitarity violation at Tevatron energies, which has been referred to as “Dino’s paradox”. We review our resoluti...
متن کاملDiffractive Production at Collider Energies I: Soft Diffraction and Dino’s Paradox
One of the more interesting developments from recent collider experiments is the finding that hadronic total cross sections as well as elastic cross sections can be described by the exchange of a “soft Pomeron” pole in the near-forward limit. The most important consequence of Pomeron being a pole is the factorization property. However, due to Pomeron intercept being greater than 1, the extrapol...

متن کاملObservation of Diffractive W - Boson Production at the Tevatron CDF
We report the first observation of diffractively produced W bosons. In a sample of W → eν events produced in p¯ p collisions at √ s=1.8 TeV, we find an excess of events with a forward rapidity gap, which is attributed to diffraction. The probability that this excess is consistent with non-diffractive production is 1.1 × 10 −4 (3.8σ). The relatively low fraction of W + Jet events observed within...
متن کاملPomeron Flux Renormalization: A scaling Law in Diffraction
The pomeron flux renormalization hypothesis is reviewed and presented as a scaling law in diffraction. Predictions for soft and hard diffraction based on pomeron flux scaling are compared with experimental results.
