Kinematic distributions of the η c leptoproduction in association with light hadrons

Journal of High Energy Physics, 2021
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 ...

Soft corrections to inclusive deep-inelastic scattering at four loops and beyond

Journal of High Energy Physics, 2020
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 ...

Rise of the DIS structure function F L at small x caused by double-logarithmic corrections

Journal of High Energy Physics, 2021
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 ...

Multivalued Memory via Freezing of Super‐Hard Magnetic Domains in a Quasi 2D‐Magnet

Small Methods, Volume 7, Issue 11, November 16, 2023., 2023
The 2D‐Ising ferromagnet BaFe2(PO4)2, is affected below 15 K by the freezing of its magnetic domains due to giant magneto‐crystalline anisotropy and intrinsic pinning of the narrow domain walls. It results in a transition from a soft to a super‐hard magnet with record‐coercive force greater than 14 T, and allows for the writing, robust locking and ...

A new approach to semi-inclusive deep-inelastic scattering with QED and QCD factorization

Journal of High Energy Physics, 2021
We present the details of a new factorized approach to semi-inclusive deep-inelastic scattering which treats QED and QCD radiation on equal footing, and provides a systematically improvable approximation to the extraction of transverse momentum dependent

Problem of the statistical model in deep inelastic scattering phenomenology [PDF]

Physics Letters B, 1993
Recent Deep Inelastic data leads to an up-down quark asymmetry of the nucleon sea. Explanations of the flavour asymmetry and the di-lepton production in proton-nucleus collisions call for a temperature $T \approx 100$ MeV in a statistical model. This T may be conjectured as being due to the Fulling-Davies-Unruh effect. But it is not possible to fit the

Advancing Our Understanding of Martian Proton Aurora Through a Coordinated Multi‐Model Comparison Campaign

Journal of Geophysical Research: Space Physics, Volume 128, Issue 10, October 2023., 2023
Abstract Proton aurora are the most commonly observed yet least studied type of aurora at Mars. In order to better understand the physics and driving processes of Martian proton aurora, we undertake a multi‐model comparison campaign. We compare results from four different proton/hydrogen precipitation models with unique abilities to represent Martian ...

Twist-2 relation and sum rule for tensor-polarized parton distribution functions of spin-1 hadrons

Journal of High Energy Physics, 2021
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

A Unifying Perspective of Common Motifs That Occur across Disparate Classes of Materials Harboring Displacive Phase Transitions

Advanced Energy Materials, Volume 13, Issue 30, August 11, 2023., 2023
This perspective reveals overarching and recurring motifs of displacive (martensitic) phase transitions such as twinned microstructure, transport anomalies, and phonon softening. However, these phase transitions are often studied in different communities; bringing them together is expected to provide opportunities for future research. Important classes
