Neutron polarisation transfer, Cx′, in π+ photoproduction off the proton, d(γ⊙,n→π+)nspec

open access: yesPhysics Letters B, 2023
We report a first measurement of the double-polarisation observable, Cx′, in π+ photoproduction off the proton. The Cx′ double-polarisation observable represents the transfer of polarisation from a circularly polarised photon beam to the recoiling ...

Using coherent dipion photoproduction to image gold nuclei

open access: yesSciPost Physics Proceedings, 2022
Vector meson photoproduction offers the opportunity to image target nuclei. The two-dimensional Fourier transform $d\sigma_{\rm coherent}/dt$ of coherent vector meson photoproduction gives the two-dimensional distribution of interaction sites in the ...

Distribution, Contents, and Types of Mycosporine-Like Amino Acids (MAAs) in Marine Macroalgae and a Database for MAAs Based on These Characteristics

open access: yesMarine Drugs, 2020
Mycosporine-like amino acids (MAAs), maximally absorbed in the wavelength region of 310−360 nm, are widely distributed in algae, phytoplankton and microorganisms, as a class of possible multi-functional compounds.

The BGOOD experiment at ELSA, exotic structures in the light quark sector? [PDF]

open access: yesEPJ Web of Conferences
The BGOOD photoproduction experiment accesses forward meson angles and low momentum exchange kinematics in the uds sector, which may be sensitive to molecular-like hadron structure.

Mechanistic insights into pH-dependent H2 photoproduction in bisulfite-treated Chlamydomonas cells

open access: yesBiotechnology for Biofuels, 2020
Background Bisulfite addition is an important H2 photoproduction strategy that removes O2 and activates hydrogenase. The pH values of cell cultures can change the ratio of bisulfite to sulfite, which may affect H2 photoproduction.

K0SΣ0 photoproduction at the BGO-OD experiment [PDF]

open access: yesEPJ Web of Conferences, 2020
The BGO-OD experiment at the ELSA accelerator facility uses an energy tagged bremsstrahlung photon beam to investigate the excitation structure of the nucleon via meson photoproduction.

Coherent pion photoproduction on spin-zero nuclei [PDF]

open access: yesEPJ Web of Conferences, 2022
We study the possibility of building a universal model describing pion scattering and photoproduction on spin-zero nuclei within the same framework. We show our prediction for photoproduction cross section based on parameters taken from our fit to pion ...

Inclusive J/ψ photoproduction at the ILC within the framework of non-relativistic QCD

open access: yesJournal of High Energy Physics, 2022
Based on the non-relativistic quantum chromodynamics factorization framework, we study the inclusive J/ψ photoproduction at the future high energy e + e − collider, International Linear Collider(ILC), where the initial photons come from the back ...

Measurement of exclusive $$\mathrm {\Upsilon }$$ Υ photoproduction from protons in $$\mathrm {p}$$ p Pb collisions at $$\sqrt{\smash [b]{s_{_{\mathrm {NN}}}}} = 5.02\,\text {TeV} $$ sNN=5.02TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The exclusive photoproduction of $$\mathrm {\Upsilon }\mathrm {(nS)} $$ Υ(nS) meson states from protons, $$\gamma \mathrm {p} \rightarrow \mathrm {\Upsilon }\mathrm {(nS)} \,\mathrm {p}$$ γp→Υ(nS)p (with $$\mathrm {n}=1,2,3$$ n=1,2,3 ), is studied in ...
