Infrared-finite factorization and renormalization scheme for exclusive processes. Application to pion form factors
N. G. Stefanis, W. Schroers, H. -Ch. Kim
We develop and discuss an infrared-finite factorization and optimized renormalization scheme for calculating exclusive processes which enables the inclusion of transverse degrees o…

Comment on the paper: ``The perturbative proton form factor reexamined'' by Kundu et al
J. Bolz, R. Jakob, P. Kroll +1
We point out some serious problems in the investigation of Kundu et al. which claims agreement with the existing data of the proton form factor, calculated without taking into acco…
