Evidence of Spin-Interference Effects in Exclusive Photoproduction in Ultraperipheral Heavy-Ion Collisions
The STAR Collaboration
We report the first evidence of spin interference in exclusive photoproduction in ultraperipheral heavy-ion collisions at STAR at ~GeV. In Au+…
Study of Central Exclusive Production of , and Pairs in Proton-Proton Collisions at GeV with the STAR Detector at RHIC
STAR Collaboration, B. E. Aboona, J. Adam +385
We report on the first measurement of the Central Exclusive Production process in proton-proton collisions: (where ) at the center-of-…
Performance of the Endcap Time-of-Flight detector in the STAR beam-energy scan
Mathias C. Labonté, Daniel Cebra, Zachary Sweger +16
The STAR experiment at RHIC at Brookhaven National Laboratory completed the installation of an endcap time-of-flight subsystem (eTOF) in February 2019. The eTOF subsystem provided…
First measurement of massive virtual photon emission from N* baryon resonances
R. Abou Yassine, J. Adamczewski-Musch, O. Arnold +127
First information on the time-like electromagnetic structure of baryons in the second resonance region has been obtained from measurements of dielectron (e+ e-) invariant-mass and…
Observation of charmonium sequential suppression in heavy-ion collisions at the Relativistic Heavy Ion Collider
STAR Collaboration, B. E. Aboona, J. Adam +370
We report measurements of charmonium sequential suppression in Ru+Ru and Zr+Zr collisions at = 200 GeV with the STAR experiment at the Relativistic Heavy…
Measuring spin correlation between quarks during QCD confinement
The STAR Collaboration
The vacuum is now understood to possess a rich and complex structure, characterized by fluctuating energy fields and a condensate of virtual quark-antiquark pairs. The spontaneous…
