First Measurement of $a_{2}^{0} (1320)$ Polarized Photoproduction Cross Section

GlueX Collaboration, F. Afzal, C. S. Akondi +149

We measure for the first time the differential photoproduction cross section $d σ / d t$ of the $a_{2} (1320)$ meson at an average photon beam energy of 8.5~GeV, using data with an integr…

Measurement of Spin-Density Matrix Elements in $Δ^{++} (1232)$ photoproduction

F. Afzal, C. S. Akondi, M. Albrecht +146

We measure the spin-density matrix elements (SDMEs) of the $Δ^{++} (1232)$ in the photoproduction reaction $γ p \to π^{-} Δ^{++} (1232)$ with the GlueX experiment in Hall D at Jefferson…

Measurement of $e^{+} e^{-} \to ω η^{'}$ cross sections at $s =$ 2.000 to 3.080 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The Born cross sections for the process $e^{+} e^{-} \to ω η^{'}$ are measured at 22 center-of-mass energies from 2.000 to 3.080 GeV using data collected with the BESIII detector…

Production of Protons and Light Nuclei in Au+Au Collisions at $s_{NN}$ = 3 GeV with the STAR Detector

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +349

We report the systematic measurement of protons and light nuclei production in Au+Au collisions at $s_{NN}$ = 3 GeV by the STAR experiment at the Relativistic Heavy…
