Aspects of con nement in total cross sections through Bloch Nordsieck soft gluon summation
نویسندگان
چکیده
An impact parameter representation for soft gluon radiation has been developed to obtain both the initial decrease in pp as well as the subsequent rise of the total cross section tot for pp and p p The rapid rise from the perturbative jets is tamed into the experimentally observed mild increase by soft gluon emission Here we focus on the role played by con nement in particular the need for a singular s in the infra red region

Hadronic Total Cross-sections Through Soft Gluon Summation in Impact Parameter Space
The Bloch-Nordsieck model for the parton distribution of hadrons in impact parameter space, constructed using soft gluon summation, is investigated in detail. Its dependence upon the infrared structure of the strong coupling constant αs is discussed, both for finite as well as singular, but integrable, αs. The formalism is applied to the prediction of total proton-proton and proton-antiproton c...

متن کاملMini-jet Total Cross-sections and Overlap Functions through Bloch-Nordsieck Summation
Predictions for total inelastic cross-sections for photon induced processes are discussed in the context of the QCD-inspired minijet model. Large theoretical uncertainties exist, some of them related to the parton distributions of hadrons in impact parameter space. A model for such distribution is presented, based on soft gluon summation. This model incorporates (the salient features of distrib...
متن کاملTotal Cross-sections and Bloch-Nordsieck Gluon Resummation
Physics Department and INFN, University of Perugia, Perugia, Italy (Received October 26, 2004) The physics underlying the fall and eventual rise in various total crosssections at high energies has been investigated over a decade using a model based on the Bloch–Nordsieck resummation in QCD. Here a brief review of our latest results is presented and comparison made with experimental data on pp, ...
متن کاملBloch-nordsieck violating electroweak corrections to inclusive TeV scale hard processes
We point out that, since the colliders' initial states ( e(+)e(-),pp, p&pmacr;,ellipsis) carry a definite non-Abelian flavor, electroweak radiative corrections to inclusive hard cross sections at the TeV scale are affected by peculiar Bloch-Nordsieck violating double logs. We recall the setup of soft cancellation theorems, and we analyze the magnitude of the noncanceling terms in the example of...
