A resolution of this tension incorporating $\ln (1/x)$ -resummation terms into the HERAPDF fits is investigated using the xFitter program. The kinematic region where this resummation is important is delineated. Such high-energy resummation not only gives a better description of the data, particularly of the longitudinal structure function $F_L$ , it also results in a gluon PDF which is steeply rising at low x for low scales, $Q^2 \simeq 2.5\,\hbox {GeV}^2$ , contrary to the fixed-order NLO and NNLO gluon PDF.}, keywords = {structure function: longitudinal (INSPIRE) / resummation (INSPIRE) / small-x (INSPIRE) / quantum chromodynamics (INSPIRE) / perturbation theory (INSPIRE) / higher-order: 1 (INSPIRE) / higher-order: 2 (INSPIRE) / DESY HERA Stor (INSPIRE) / data analysis method (INSPIRE) / statistical analysis (INSPIRE) / tension (INSPIRE) / gluon: distribution function (INSPIRE) / deep inelastic scattering (INSPIRE) / DGLAP equation (INSPIRE) / kinematics (INSPIRE)}, cin = {CMS / ATLAS}, ddc = {530}, cid = {I:(DE-H253)CMS-20120731 / I:(DE-H253)ATLAS-20120731}, pnm = {611 - Fundamental Particles and Forces (POF3-611)}, pid = {G:(DE-HGF)POF3-611}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)29 / PUB:(DE-HGF)16}, eprint = {1802.00064}, howpublished = {arXiv:1802.00064}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1802.00064;\%\%$}, UT = {WOS:000440761300001}, doi = {10.1140/epjc/s10052-018-6090-8}, url = {https://bib-pubdb1.desy.de/record/417110}, }
