Charmed hadron photoproduction at COMPASS

open access: yesOpen Physics, 2016
Photoproduction of the charmonium-like state Zc(4200) and the charmed baryon Λc*$\it\Lambda _c^*$(2940) is investigated with an effective Lagrangian approach and the Regge trajectories applying to the COMPASS experiment.

Designing Molecular Solar Thermal Systems Based on the Paternò-Büchi Reaction Coupled to Enzymatic Energy Release. [PDF]

open access: yesChemSusChem
Molecular solar thermal systems urge for innovative building blocks to increase their present limits in storage density and light activation window. Here, a complete computational study of loading and unloading mechanisms for an experimentally inspired system based on the Paternò–Büchi reaction is presented.

Factorization Breaking in Dijet Photoproduction with a Leading Neutron [PDF]

open access: yes, 2006
The production of dijets with a leading neutron in ep-interactions at HERA is calculated in leading order and next-to-leading order of perturbative QCD using a pion-exchange model.

Spectrally resolved efficiencies of carbon monoxide (CO) photoproduction in the western Canadian Arctic: particles versus solutes [PDF]

open access: yesBiogeosciences, 2013
Spectrally resolved efficiency (i.e. apparent quantum yield, AQY) of carbon monoxide (CO) photoproduction is a useful indicator of substrate photoreactivity and a crucial parameter for modeling CO photoproduction rates in the water column.

First study of the initial gluonic fluctuations using UPCs with ALICE [PDF]

open access: yesEPJ Web of Conferences
Incoherent and dissociative J/ψ photoproduction is sensitive to fluctuations of the gluonic structure of the target. Thus, the measurement of Jψ photoproduction of the colliding hadron sheds light on the initial state of QCD and provides important ...

Measurement of the beam-helicity asymmetry in photoproduction of π0η pairs on carbon, aluminum, and lead

open access: yesPhysics Letters B, 2020
The beam-helicity asymmetry was measured, for the first time, in photoproduction of π0η pairs on carbon, aluminum, and lead, with the A2 experimental setup at MAMI.

Coherent photoproduction of $J/\psi$ in nucleus-nucleus collisions \\in the color dipole approach- an update

open access: yesSciPost Physics Proceedings, 2022
We discuss the role of $c \bar c g$-Fock states in the diffractive photoproduction of $J/\psi$-mesons. We build on our earlier description of the process in the color-dipole approach, where we took into account the rescattering of $c \bar c$ pairs ...

Generation of High-Brilliance Polarized γ-Rays Via Vacuum Dichroism-Assisted Vacuum Birefringence. [PDF]

open access: yesAdv Sci (Weinh)
A novel method is proposed for generating such γ‐photon beams via the vacuum‐dichroism‐assisted quantum vacuum birefringence effect, only utilizing well‐established unpolarized electron beams and solving the critical problem of demanding polarized ones.
