New parton model for the soft interactions at high energies: The odderon

the use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach

abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...

Photon Interactions Liverpool, at High Energies

Hadronic photon-photon interactions at high energies.

Photon-photon collisions are investigated in the framework of the two-component Dual Parton Model. The model contains contributions from direct, resolved soft and resolved hard interactions. All free parameters of the model are determined in fits to hadronhadron and photon-hadron cross section data. The model is shown to agree well to hadron production data from hadron-hadron and photon-hadron ...

Soft Interactions at High Energy

Soft interactions are not easily disentangled from hard ones. In an operational definition of soft and hard processes one finds that at presently analyzed scales there is an interplay of soft and hard processes. As the scale increases, so does the amount of hard processes. So far, nothing is as soft nor as hard as we would like.

Parton-Parton Elastic Scattering and Rapidity Gaps at Very High Energies

The theory of the perturbative pomeron, due to Lipatov and collaborators, is used to compute the probability of observing parton-parton elastic scattering and rapidity gaps between jets in hadron collisions at very high energies. Submitted to Physics Letters B ? Work supported by the Department of Energy, contract DE–AC03–76SF00515. The energies of the Tevatron, LHC and SSC colliders open a win...
