Flavoring of Pomeron and Diffractive Production at Tevatron Energies
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 VIIth Blois Workshop on Elastic and Diffractive Scattering, Seoul, Korea, (1997).

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 کاملFactorization breaking in diffractive dijet production
We study diffractive hard dijet production, with one or two rapidity gaps, at high energies. We emphasize that both hard and Regge factorization are broken in these processes. We show that a multi-Pomeron-exchange model for screening effects gives a specific pattern for the breakdown of factorization, which is in good agreement with diffractive dijet data collected at the Tevatron. The investig...
متن کاملHard diffractive quarkonium hadroproduction at high energies
We present a study of heavy quarkonium production in hard diffractive processes by pomeron exchange for Tevatron and LHC energies. The numerical results are computed using a recent experimental determination of the diffractive parton density functions in the pomeron and these are corrected by unitarity corrections through the gap survival probability factor. We give predictions for single as we...
