Detailed Description

Collection of the neutral current massless limit of the massive coefficient functions for F2 and FL up to O(αs).

Note
In the following "xi" indicates the ratio Q2 / M2 and "xiF" is equal to M2 / μF2. See Appendix D of https://arxiv.org/pdf/hep-ph/9601302.pdf. The suffix "_c" in the classes below stands for "constant", that is no dependence on "xi" or "xiF". "_l" or "_l2" instead means that that term is proportional to log(xi) or log2(xi), respectively. While "_f" means proportional to log(xiF) amd "_lf" proportional to log(xi)log(xiF).
