Photoproduction and electroproduction of charm at high energies

, 2000
We estimate the differential and total cross sections for both the photoproduction of vector D*-meson and its yield in deep inelastic scattering at the HERA collider in the framework of model motivated by perturbative calculations in QCD.

QCD Corrections to Inelastic $J/\psi$ Photoproduction [PDF]

, 1995
We present a complete calculation of the higher-order perturbative QCD corrections to inelastic photoproduction of $J/\psi$ particles. A comprehensive analysis of total cross sections and differential distributions for the energy range of the fixed ...

Cutaneous photosensitivity of phototheranostic porphyrin–lipid nanoparticles

Photochemistry and Photobiology, Volume 101, Issue 6, Page 1541-1558, November/December 2025.
Porphyrin‐lipid nanoparticles (PORPHYSOMES) exhibit significantly less severe and shorter‐lasting skin photosensitivity to sunlight compared to a therapeutically equivalent dose of porfimer sodium (PHOTOFRIN) in a rat skin model. The difference was due to altered intradermal distribution and faster clearance of PORPHYSOMES from skin after intravenous ...

Update on Partial-Wave Analysis

, 2001
Partial-wave analysis is one step in a process connecting experimental measurements to the N* states we are studying. Progress has been made in the area of `model-independent' analysis. However, more model-dependent approaches are needed to cover broader

Color-Octet Contributions to J/psi Photoproduction via Fragmentation at HERA [PDF]

, 1997
We study J/psi photoproduction via fragmentation at next-to-leading order in the QCD-improved parton model, using the nonrelativistic factorization formalism proposed by Bodwin, Braaten, and Lepage.

Ionic Metal Poly(heptazine Imides) and Single‐Atoms Interplay: Engineered Stability and Performance for Photocatalysis, Photoelectrocatalysis and Organic Synthesis

Advanced Functional Materials, Volume 35, Issue 44, October 29, 2025.
Poly(heptazine) imides (PHIs), a crystalline carbon nitride subclass, intercalate metals to deliver high stability, tunable electronics, and efficient charge separation. These features enable solar‐driven applications such as hydrogen evolution, CO₂ reduction, and organic synthesis.

Recent diffractive results from HERA

EPJ Web of Conferences, 2016
The diffractive dijet cross sections for photoproduction and deep inelastic scattering were studied and compared with theoretical NLO QCD predictions. The results of exclusive dijet production were compared to predictions from models which are based on ...

Spin rotation effects in diffractive electroproduction of heavy quarkonia

European Physical Journal C: Particles and Fields, 2019
In this work we present for the first time the comprehensive study of the Melosh spin rotation effects in diffractive electroproduction of S-wave heavy quarkonia off a nucleon target. Such a study has been performed within the color dipole approach using,

Ultra-peripheral collisions and hadronic structure

, 2017
Ultra-peripheral collisions are the energy frontier for photon-mediated interactions, reaching, at the Large Hadron Collider (LHC), $\gamma-p$ center of mass energies five to ten times higher than at HERA and reaching $\gamma\gamma$ energies higher than ...
