    Two-gluon exchange graphs in cavity QCD to order αs2
    (1998) Schumann, Marc; Viollier, Raoul D
    The purpose of this thesis is to go beyond the usual first order calculations and to evaluate the two-gluon exchange diagrams, which are second order in as. Two distinct Feynman diagrams exist, of which each consists of twenty-four timeordered diagrams. All the possible time-ordered diagrams are calculated here. A similar calculation of only the first six time-ordered diagrams has been performed by Stoddart et al.The purpose of this thesis is to go beyond the usual first order calculations and to evaluate the two-gluon exchange diagrams, which are second order in αs.
