Large-momentum behaviour and analyticity in the coupling constant
The general solution of the differential equation for a vertex mass insertion which is manifestly regular at zero external momenta is given. The large-momentum behaviour of the solution and its analyticity properties in the coupling constant are discussed. Very different results are found for superr...
