DIS structure functions in the NLO approximation of the Parton Reggeization Approach
The main ideas of the NLO calculations in Parton Reggeization Approach are
illustrated on the example of the simplest NLO subprocess, which contributes to
DIS: . The double counting with the LO
contribution is resolved. The problem of matching of
the NLO results for single-scale observables in the Parton Reggeization
Approach on the corresponding NLO results in the Collinear Parton Model is
considered. In the developed framework, the usual NLO PDFs in the
-scheme can be consistently used as the collinear input for the
NLO calculation in the Parton Reggeization Approach.Comment: 10 pages, 2 figures, Talk at the QFTHEP-2017, June, 2017, Yaroslavl,

Heavy quarkonium production at the LHC in the framework of NRQCD and parton Reggeization approach
Heavy quarkonium production in the framework of the nonrelativistic quantum
chromodynamics and leading order of the parton Reggeization approach at the
Tevatron and LHC Colliders is discussed. The new results, which are reviewed in
this report, include the comparison with recent data on chi_{c1,c2} production
from ATLAS Collaboration and special discussion of heavy quarkonium
polarization issues in the considered framework.Comment: 5 pages, 2 figures. Talk at the Helmholtz International Summer School
