Non-Perturbative Regge Exchange in Meson-Meson Scattering: An Analysis Based on the Stochastic Vacuum Model
A. I. Karanikas, C. N. Ktorides
Employing the Worldline casting of the Dosch-Simonov Stochastic Vacuum Model(SVM) for QCD, a simulated meson-meson scattering is studied in the Regge kinematical regime. The proces…
Analyticity of QCD observables beyond leading-order perturbation theory
N. G. Stefanis, A. I. Karanikas
A theoretical framework is presented to treat hadronic observables within analytic perturbative QCD beyond the leading order of the coupling and for more than one single large mome…
Analyticity properties of three-point functions in QCD beyond leading order
A. P. Bakulev, A. I. Karanikas, N. G. Stefanis
The removal of unphysical singularities in the perturbatively calculable part of the pion form factor--a classic example of a three-point function in QCD--is discussed. Different `…
Non-perturbative corrections to perturbative results pertaining to a four-point Sudakov process in QCD
A. I. Karanikas, C. N. Ktorides
Within the framework of the Fock-Feynman-Schwinger (equivalently, worldline) casting of QCD a four-point process, mediated by a closed quark loop, is studied in the Sudakov kinemat…
Resummation of perturbatively enhanced gluon radiative corrections
A. I. Karanikas, C. N. Ktorides, N. G. Stefanis
By remaining strictly within the confines of QCD, i.e., {\it without} invoking the parton model or any other exogenous element, we identify and resum perturbatively to leading orde…
Worldline description of the Isgur-Wise function
N. G. Stefanis, A. I. Karanikas, C. N. Ktorides
An effective field theoretic description of the Isgur-Wise function in heavy-meson transitions is presented which emulates soft interactions by a fermion worldline with an infinite…
