Soft Physics – Three Pomerons?
نویسندگان
چکیده
A model of a three Pomeron contribution to high energy elastic pp and p̄p scattering is proposed. The data are well described for all momenta (0.01 ≤ |t| ≤ 14. GeV 2) and energies (8. ≤ √s ≤ 1800. GeV ) (χ2/d.o.f. = 2.60). The model predicts the appearance of two dips in the differential cross-section which will be measured at LHC. The parameters of the Pomeron trajectories are: α(0)P1 = 1.058, α ′(0)P1 = 0.560 (GeV −2); α(0)P2 = 1.167, α ′(0)P2 = 0.273 (GeV −2); α(0)P3 = 1.203, α ′(0)P3 = 0.094 (GeV −2).

Pomeron physics: an update
Key issues in pomeron physics include whether the hard and soft pomerons are distinct objects, and whether the hard pomeron is already present in amplitudes at Q = 0. It is urgent to learn how to combine perturbative and nonperturbative concepts, and to construct a sound theory of perturbative evolution at small x. Other questions are whether screening corrections are small, and gap survival pr...

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. We show that...
متن کاملAbout the Behaviour of Qcd Pomeron in Deep Inelastic Scattering
The paper presents the QCD description of the small x behaviour of parton distribution functions in the leading twist of Wilson operator product expansion. The smooth transition between the cases of the soft and hard Pomerons is obtained. The results are in qualitative agreement with deep inelastic experimental data. PACS number(s): 13.60.Hb, 12.38.Bx, 13.15.Dk 1 On leave of absence from Partic...
