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…
A numerical algorithm for computing the complete set of one-gluon loop diagrams in QCD on the basis of a single master expression
A. S. Kapoyannis, A. I. Karanikas, C. N. Ktorides
A numerical program is presented which facilitates the computation of the full set of one-gluon loop diagrams (including ghost loop contributions), with M attached external gluon l…
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…
N Delta - Transition Form Factors at Low Momentum Transfer
G. C. Gellas, T. R. Hemmert, C. N. Ktorides +1
The three complex form factors entering the vertex are calculated to in the framework of a chiral effective theory with explicit (1232) degrees of…
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…
