The Contribution of Methane Photoproduction to the Oceanic Methane Paradox
Although methanogenesis is considered a strictly anaerobic process, oxygen‐replete surface open‐ocean waters are usually supersaturated with methane (CH4), a phenomenon termed the oceanic methane paradox.

Eta and Etaprime Photoproduction on the Nucleon with the Isobar Model EtaMAID2018 [PDF]
The isobar model EtaMAID has been updated with new and high precision data for η and η′ photoproduction on protons and neutrons from MAMI, ELSA, GRAAL and CLAS.

The impact of final-state interaction on the πΣ photoproduction in the Λ(1405) region [PDF]
It was recently demonstrated [1] that the meson-baryon rescattering in the final state has a major impact on the magnitude and structure of the πΣ mass distributions observed in the γp → K+πΣ photoproduction.

Exclusive Vector Photoproduction: Confirmation of Regge Theory [PDF]
Recent small-t ZEUS data for exclusive rho photoproduction are in excellent agreement with exchange of the classical soft pomeron with slope alpha'=0.25 GeV^{-2}. Adding in a flavour-blind hard-pomeron contribution, whose magnitude is calculated from the

Photoproduction of $\eta$ mesons off neutrons from a deuteron target [PDF]
A formalism is developed for the partial wave analysis of data on meson photoproduction off deuterons and applied to photoproduction of $\eta$ and $\pi^0$ mesons.

Inelastic photoproduction [PDF]
Inelastic photoproduction of $J/ $ particles at high energies is one of the processes to determine the gluon distribution in the nucleon. We have calculated the QCD radiative corrections to the color-singlet model of this reaction. They are large at moderate photon energies, but decrease with increasing energies.

Some selected topics in photoproduction are reviewed. In particular, the focus is on quasi-real photon-proton scattering as measured at HERA. Single & dijet rates and jet profiles are discussed, as are open charm production and inelastic charmonium production.

A Stepwise NaHSO3 Addition Mode Greatly Improves H2 Photoproduction in Chlamydomonas reinhardtii
NaHSO3 addition greatly increases the yield of H2 photoproduction in a unicellular green alga Chlamydomonas reinhardtii through removing O2 and activating hydrogenase but significantly impairs the activity of PSII, an electron source for H2 ...

Photoproduction of hidden charm pentaquark states $P_c^+(4380)$ and $P_c^+(4450)$ [PDF]
We propose to study the pentaquark candidates of $P_c^+(4380)$ and $P_c^+(4450)$ in $J/\psi$ photoproduction and look for further experimental evidence for their nature. Since the photoproduction process does not satisfy the so-called "anomalous triangle
