Soft corrections to inclusive deep-inelastic scattering at four loops and beyond
We study the threshold corrections for inclusive deep-inelastic scattering (DIS) and their all-order resummation. Using recent results for the QCD form factor, related anomalous dimensions and Mellin moments of DIS structure functions at four loops we ...

Twist-2 relation and sum rule for tensor-polarized parton distribution functions of spin-1 hadrons
Sum rules for structure functions and their twist-2 relations have important roles in constraining their magnitudes and x dependencies and in studying higher-twist effects. The Wandzura-Wilczek (WW) relation and the Burkhardt-Cottingham (BC) sum rule are

Kinematic distributions of the η c leptoproduction in association with light hadrons
The η c meson leptoproduction is calculated within the nonrelativistic QCD framework for the first time. It is found that the colour-singlet channel, although suppressed by a factor of α s relative to the colour-octet ones, provides important ...

Rise of the DIS structure function F L at small x caused by double-logarithmic corrections
We present calculation of F L in the double-logarithmic approximation (DLA) and demonstrate that the synergic effect of the factor 1/x from the α s 2 $$ {\alpha}_s^2 $$ -order and the steep x-dependence of the totally resummed double logarithmic ...

Semi-Exclusive Pion Production in Deep-Inelastic Scattering [PDF]
We calculate azimuthal asymmetries and the Callan-Gross $R$-ratio for semi-exclusive pion production in deep inelastic scattering taking into account higher twist effects. Our results are qualitatively different from the QCD-improved parton model predictions for semi-inclusive deep inelastic scattering.

Deep inelastic scattering in conformal QCD [PDF]
We consider the Regge limit of a CFT correlation function of two vector and two scalar operators, as appropriate to study small-x deep inelastic scattering in N=4 SYM or in QCD assuming approximate conformal symmetry. After clarifying the nature of the Regge limit for a CFT correlator, we use its conformal partial wave expansion to obtain an impact ...

In Sect. 5.5 we discussed the spectra observed in electron scattering off nuclei. As well as the elastic scattering peak some additional peaks, which we associated with nuclear excitations, were observed. Similar spectra are observed for electron-nucleon scattering.

Photon–jet correlations in deep-inelastic scattering
The reaction $$e + p \rightarrow \gamma + \mathrm{jet} + X$$ e + p → γ + jet + X is studied in QCD at the next-to-leading order. Previous studies on inclusive distributions showed good agreement with ZEUS data.

Study of $D^{*+/-}$ Meson Production in Diffractive $ep$ Scattering at HERA [PDF]
$D^{*+/-}$ production in the diffractive interactions was measured with the ZEUS detector at HERA using integrated luminosities of 44 pb$^{-1}$ in deep inelastic scattering and 38 pb$^{-1}$ in photoproduction processes.
