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…

Nonperturbative calculation of Green and vertex functions in terms of particle contours
N. G. Stefanis
The infrared regime of fermionic Green and vertex functions is studied analytically within a geometric approach which simulates soft interactions by an {\it effective} theory of co…

End-Point Behavior of Exclusive Processes: The Twilight Regime of Perturbative QCD
N. G. Stefanis
A selected set of topics along the borderline between perturbative and nonperturbative QCD in exclusive reactions are studied. Specific problems, related to different mechanisms of…
