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+…

Measurement of transverse polarization of and hyperons inside jets in collisions at GeV
STAR Collaboration, B. E. Aboona, J. Adam +363
A surprisingly large transverse polarization of hyperons in unpolarized hadron-nucleon/nucleus collisions has been observed for 50 years, and the origin of this polarization r…

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…
