Analytical results in ancillary FORM file}, abstract = {We have computed the four lowest even-N moments of all four splitting functions for the evolution of flavour-singlet parton densities of hadrons at the fourth order in the strong coupling constant αs. The perturbative expansion of these moments, and hence of the splitting functions for momentum fractions x≳0.1, is found to be well behaved with relative αs-coefficients of order one and sub-percent effects on the scale derivatives of the quark and gluon distributions at αs≲0.2. More intricate computations, including other approaches such as the operator-product expansion, are required to cover the full x-range relevant to LHC analyses. Our results are presented analytically for a general gauge group for detailed checks and validations of such future calculations.}, keywords = {strong interaction: coupling constant (INSPIRE) / parton: density (INSPIRE) / evolution equation (INSPIRE) / DGLAP equation (INSPIRE) / splitting function (INSPIRE) / operator product expansion (INSPIRE) / quantum chromodynamics (INSPIRE) / quark (INSPIRE) / gluon (INSPIRE) / perturbation theory (INSPIRE) / higher-order: 4 (INSPIRE) / Mellin transformation (INSPIRE)}, cin = {UNI/TH}, ddc = {530}, cid = {$I:(DE-H253)UNI_TH-20120731$}, pnm = {899 - ohne Topic (POF4-899)}, pid = {G:(DE-HGF)POF4-899}, experiment = {EXP:(DE-H253)LHC-Exp-ATLAS-20150101 / EXP:(DE-H253)LHC-Exp-CMS-20150101}, typ = {PUB:(DE-HGF)16}, eprint = {2111.15561}, howpublished = {arXiv:2111.15561}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:2111.15561;\%\%$}, UT = {WOS:000778434900003}, doi = {10.1016/j.physletb.2021.136853}, url = {https://bib-pubdb1.desy.de/record/481428}, }
