Reggeized Quark Multiperipheral Model for Dual Sheets

/ 07 01 14 4 v 1 1 8 Ja n 20 07 Radiative corrections to the Reggeized quark – Reggeized quark – gluon effective vertex ⋆

This paper is devoted to the calculation of the Reggeized quark – Reggeized quark – gluon effective vertex in perturbative QCD in the next–to–leading order. The case of QCD with massless quarks is considered and the correction is obtained in theD → 4 limit. This vertex appears in the quark Reggeization theory, which next–to–leading order extension is now under construction.

Unitary Multiperipheral Models*

The method of constructing unitary S-matrices developed in a recent paper is generalized and applied to two versions of the multiperipheral model. In these models the standard perturbation expansion of the S-matrix diverges, so an alternative expansion with improved convergence properties is developed. It is shown that the unitarity condition generates a new type of cut in the angular momentum ...

Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties

So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...

A Constituent Quark Anti-quark Effective Lagrangian Based on the Dual Superconducting Model of Long Distance Qcd

We review the assumptions leading to the description of long distance QCD by a Lagrangian density expressed in terms of dual potentials. We find the color field distribution surrounding a quark anti-quark pair to first order in their velocities. Using these distributions we eliminate the dual potentials from the Lagrangian density and obtain an effective interaction Lagrangian LI(~x1 , ~x2 ;~v1...
