Threshold resummation for DIS, Drell-Yan, Higgs production and SIA (…, 2009)

NOTE: misprints in Eqs. (4.8), (5.6), (5.7) and (5.9) of hep-ph/0506288 have been corrected in the ps-file linked above and on arXiv.org

Full N3LL + N3LO accuracy has been reached in 2014 also for Higgs and lepton-pair production by Anastasiou et al, arXiv:1403.4616 = Phys. Lett. B737 (2014) 325-328, and Ahmed et al, arXiv:1404.0366 = Phys. Rev. Lett. 113 (2014) 112002.


Three-loop form factors of massless quarks and gluons (2005)

For a conference overview over both topics, see hep-ph/0511113 (Acta Phys. Polon. B36 (2005) 3295).

A deeper understanding of the relation between the form factor and the δ(1-x) contribution to the splitting functions in (21) - (25) of hep-ph/0508055 has been provided by Dixon, Magnea and Sterman in arXiv:0805.3515 = JHEP 08 (2008) 022.

The calculation of these form factors was extended by others beyond the pole terms in 2009/10, see Baikov et al, arXiv:0902.3519 = Phys. Rev. Lett. 102 (2009) 212002; Lee, Smirnov and Smirnov, arXiv:1001.2887 = JHEP 1004 (2010) 020; Gehrmann et al, arXiv:1004.3653 = JHEP 1006 (2010) 094.
