Measurement of the near-threshold J photoproduction cross section with the CLAS12 experiment
P. Chatagnon, V. Kubarovsky, R. Paremuzyan +147
We present measurements of the total and differential cross sections for near-threshold J/ photoproduction obtained with the CLAS12 detector at the Thomas Jefferson National Acc…
Measurement of the Total Compton Scattering Cross Section between 6.5 and 11 GeV
GlueX Collaboration, F. Afzal, C. S. Akondi +148
The total cross section for Compton scattering off atomic electrons, , was measured using photons with energies between 6.5 and 11.1 GeV incident on a Be t…
First Measurement of Near- and Sub-Threshold Photoproduction off Nuclei
J. R. Pybus, L. Ehinger, T. Kolar +65
We report on the first measurement of photoproduction from nuclei in the photon energy range of to GeV, extending above and below the photoproduction threshold in…
Measurement of Spin-Density Matrix Elements in photoproduction
F. Afzal, C. S. Akondi, M. Albrecht +146
We measure the spin-density matrix elements (SDMEs) of the in the photoproduction reaction with the GlueX experiment in Hall D at Jefferson…
Upper Limit on the Photoproduction Cross Section of the Spin-Exotic
GlueX Collaboration, F. Afzal, C. S. Akondi +147
The spin-exotic hybrid meson is predicted to have a large decay rate to the final state. Using 76.6~pb of data collected with the GlueX detector, we meas…
Using graph neural networks to reconstruct charged pion showers in the CMS High Granularity Calorimeter
M. Aamir, G. Adamov, T. Adams +568
A novel method to reconstruct the energy of hadronic showers in the CMS High Granularity Calorimeter (HGCAL) is presented. The HGCAL is a sampling calorimeter with very fine transv…
