An NLO QCD analysis of inclusive cross-section and jet-production data from the ZEUS experiment
The ZEUS inclusive differential cross-section data from HERA, for charged and neutral current processes taken with e
+ and e
- beams, together with differential cross-section data on inclusive jet production in e
+
p scattering and dijet production in scattering, have been used in a new NLO QCD analysis to extract the parton distribution functions of the proton. The input of jet-production data constrains the gluon and allows an accurate extraction of
at NLO;
An additional uncertainty from the choice of scales is estimated as
. This is the first extraction of
from HERA data alone.
