“…The role of the real part has been admitted only as a small partial fraction of corresponding imaginary part, i.e., the number of its contributing terms has been smaller than n (as, e.g., in [7,10,11,15]); or specified with the help of derivative dispersion relations as in [9,[12][13][14]18]. Also additional linear logarithmic t-dependencies of all quantities β j (s) and quadratic logarithmic t-dependencies of all quantities α j (s) have been introduced in order to better reproduce the corresponding differential cross section.…”
