A Tale of Two Hard Pomerons
نویسنده
چکیده
Two mechanisms are examined for hard double pomeron exchange dijet production, the factorized model of Ingelman-Schlein and the nonfactorized model of lossless jet production which exhibits the Collins-Frankfurt-Strikman mechanism. Comparison between these two mechanisms are made of the total cross section, ET -spectra, and mean rapidity spectra. For both mechanisms, several specific models are examined with the cuts of CDF, DØ and representative cuts of LHC. The preliminary CDF and DØ data for this process are interpreted in terms of these two mechanisms. The experimental data is suggestive of a dominant component of the factorized Ingelman-Schlein mechanism, although as is discussed there are some inconsistencies. PACS number(s): 13.85.-t, 12.38.Qk, 13.87.Ce

We quantify the central inclusive background contributions to exclusive Higgs production at the LHC arising from double-Pomeron-exchange processes. We consider the H → bb̄ signal. We study processes mediated by the fusion of two ‘hard’ Pomerons, and also by the fusion of ‘soft’ Pomerons. The latter background is found to be very small, and the former is found to be less than the exclusive signal...

We consider simple-pole descriptions of soft elastic scattering for pp, p̄p, πp and Kp. We work at t and s small enough for rescatterings to be neglected, and allow for the presence of a hard pomeron. After building and discussing an exhaustive dataset, we show that simple poles provide an excellent description of the data in the region −0.5 GeV2 ≤ t ≤ −0.1 GeV2, 6 GeV≤ √s ≤ 63 GeV.

متن کاملAn Architectural Tale of the Two Cities
A comparative study of the corresponding styles of Western and Iranian modern architecture has hardly ever been carried out in detail. This paper aims to sketch out an outline for such an investigation and to present a summary of empirical evidence accompanied by field observations to elaborate the ongoing trend of relationship between architectural styles in Iran and that of the West. This is ...
متن کاملSpin constraints on Regge predictions and perturbative evolution in high energy collisions
Two key issues in the application of perturbative QCD and Regge predictions to high energy processes are whether the hard and soft pomerons should be considered as two separate distinct exchanges and whether the Regge intercepts are Q2 independent or not. Models involving a distinct hard pomeron exchange predict much larger values for the LHC total cross-section. Here we argue that there is a p...
