Query: Influence of gluon behavior on heavy-quark pair production   We check the impact of the gluon distribution due to the number of active
flavor employed in the calculation of heavy-quark deep-inelastic scattering
(DIS) electro-production on the reduced cross section and structure functions
determined in the leading order (LO) and next-to-leading order (NLO) quantum
chromodynamics (QCD) analysis using the Hadron Electron Ring Accelerator (HERA)
combined data. The charm and beauty structure functions are determined and
compared with the HERA combined data. The results are in good agreement with
respect to the experimental data. We also compare the obtained charm and bottom
structure functions with the results from CTEQ6.6 [Phys.Rev.D{\bf78},
013004(2008)] and NNPDF3.1[Eur.Phys.J.C{\bf77}, 663(2017)] parameterization
models. The effect of gluon density on these calculations depends on the number
of active flavor at asymptotical values of the momentum transfer $Q^{2}$. Also,
in the HERA kinematic range, the ratio of $F_{2}^{c\overline{c}}/F_{2}$ and
$F_{2}^{b\overline{b}}/F_{2}$ are obtained. These results and comparison with
the HERA combined data demonstrate that the suggested method can be applied in
analysis of new colliders.
