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…
