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 $Δ \to N γ^{*}$ vertex are calculated to $O (ε^{3})$ in the framework of a chiral effective theory with explicit $Δ$ (1232) degrees of…

Worldline approach to Sudakov-type form factors in non-Abelian gauge theories

G. C. Gellas, A. I. Karanikas, C. N. Ktorides +1

We calculate Sudakov-type form factors for isolated spin-1/2 particles (fermions) entering non-Abelian gauge-field systems. We consider both the on- and the off-mass-shell case usi…
