...In order to gain further confidence in the emergence of a minus sign in the asymptotic representation (522), as well as to understand how this observation relates to the pure singlet Wilson coefficients at 2-loop order, the calculation of leading logarithmic contributions is performed using the method also applied by Altarelli and Parisi [34], cf. also [334]....
