Structure‐Function Relationships of Biomass‐Derived Materials for Zinc Metal Protection
This review analyses the mechanism of zinc anode degradation, focuses on the protective roles of the four major functional groups of carboxyl, amino, hydroxyl, and sulfonic acid groups in biomass materials, reveals the structure‐function relationship and synergistic effects of functional groups, and looks forward to the challenges and directions of ...

On the power divergence in quasi gluon distribution function
Recent perturbative calculation of quasi gluon distribution function at one-loop level shows the existence of extra linear ultraviolet divergences in the cut-off scheme.

QCD at the amplitude level: Fock state interference in heavy quark electroproduction
Quantum chromodynamics (QCD) rigorously predicts the existence of both nonperturbative intrinsic and perturbative extrinsic heavy quark contents of nucleons.

Where do perturbative and non-perturbative QCD meet? [PDF]
We computed the static potential and Wilson loops to $O(\alpha^2)$ in perturbation theory for different lattice quark and gluon actions. In general, we find short distance lattice data to be well described by ``boosted perturbation theory''.

S-wave ground state charmonium decays of $B_c$ mesons in the perturbative QCD approach [PDF]
We make a systematic investigation on the two-body nonleptonic decays $B_c\rightarrow J/\Psi(\eta_c),M$ by employing the perturbative QCD approach based on $k_T$ factorization, where $M$ is a light pseudoscalar or vector or a heavy charmed meson.

ABSTRACT The physics of heavy‐ion collisions is one of the most exciting and challenging directions of science for the last four decades. On the theoretical side one deals with a non‐abelian field theory, while on the experimental side today's largest accelerators are needed to enable these studies.

A Modern View of Perturbative QCD and Application to Heavy Quarkonium Systems [PDF]
Perturbative QCD has made significant progress over the last few decades. In the first part, we present an introductory overview of perturbative QCD as seen from a modern viewpoint.

Partonic Picture of Nuclear Shadowing at Small x [PDF]
We investigate the nuclear shadowing mechanism in the context of perturbative QCD and the Glauber multiple scattering model. Using recent HERA data on nucleon structure function at small $x$, we put stringent constrains on the nucleon gluon density in ...

Direct CP asymmetries of three-body $B$ decays in perturbative QCD [PDF]
We propose a theoretical framework for analyzing three-body hadronic B meson decays based on the perturbative QCD approach. The crucial nonperturbative input is a two-hadron distribution amplitude for final states, whose timelike form factor and ...

Higgs boson production in association with a jet at next-to-next-to-leading order in perturbative QCD [PDF]
We report on a calculation of the cross-section for Higgs boson production in gluon fusion in association with a hadronic jet at next-to-next-to-leading order (NNLO) in perturbative QCD. The computational technique is discussed in detail.
