Forward scattering amplitudes in semi-hard QCD

B Margolis, P Valin, MM Block, F Halzen, RS Fletcher - Physics Letters B, 1988 - Elsevier
We argue that the observation by UA4 of a high energy ρ value (real-to-imaginary ratio of the
forward pp amplitude) in excess of what had been predicted is accommodated by QCD. At …

Semi-hard QCD: Minijets and elastic scattering

JD De Deus, J Kwiecinski - Physics Letters B, 1987 - Elsevier
Starting from the QCD calculation of the amplitude for semi-hard interactions we establish a
quantitative correlation between the growth of the cross section for minijet production and …

Cross sections for semihard interactions in hardronic collisions beyond the leading order of perturbative QCD

J Kwieciński - Physics Letters B, 1987 - Elsevier
An estimate of cross sections which correspond to semihard interactions such as gluon
(mini) jet production is presented. It takes into account recent results concerning gluon …

Semihard QCD and high-energy and scattering

L Durand, H Pi - Physical Review D, 1989 - APS
We present the results of an analysis of high-energy pp and pp scattering based on a model
in which the energy dependence of very-high-energy processes is driven by semihard …

The underlying event in hard scattering processes

RD Field - arXiv preprint hep-ph/0201192, 2002 - arxiv.org
We study the behavior of the" underlying event" in hard scattering proton-antiproton
collisions at 1.8 TeV and compare with the QCD Monte-Carlo models. The" underlying …

Quark elastic scattering as a source of high-transverse-momentum mesons

RD Field, RP Feynman - Physical Review D, 1977 - APS
We investigate the consequences of the assumption that the high-transverse-momentum
particles seen in hadron-hadron collisions are produced by a single, hard, large-angle …

Unitarity constraints on semihard jet production in impact parameter space

TC Rogers, AM Staśto, MI Strikman - Physical Review D—Particles, Fields …, 2008 - APS
The perturbative QCD formula for minijet production constitutes an important ingredient in
models describing the total cross section and multiparticle production in hadron-hadron …

Low-pt jets and the rise with energy of the inelastic cross section

G Pancheri, YN Srivastava - Physics Letters B, 1986 - Elsevier
The contribution of QCD jets to the rise with energy of the inelastic cross section is discussed
quantitatively and found to be large. It is seen that the inclusive jet yield is the fastest …

QCD and rising cross sections

L Durand, P Hong - Physical Review Letters, 1987 - APS
We show that parton-parton scattering processes in QCD drive a rapid increase in the proton-
proton scattering cross section at high energies, and use a diffraction-scattering formalism to …

Theoretical implications of Fermilab Tevatron total and elastic differential-cross-section measurements

M Block, R Fletcher, F Halzen, B Margolis, P Valin - Physical Review D, 1990 - APS
Production of gluon jets becomes a feature of average hadron collisions for multi-TeV
energies, leading to a model where interactions are mostly mediated by semihard gluons …
