Evidence of Spin-Interference Effects in Exclusive $J / ψ \to e^{+} e^{-}$ Photoproduction in Ultraperipheral Heavy-Ion Collisions

The STAR Collaboration

We report the first evidence of spin interference in exclusive $J / ψ \to e^{+} e^{-}$ photoproduction in ultraperipheral heavy-ion collisions at STAR at $s_{N N} = 200$ ~GeV. In Au+A…

Measurement of transverse polarization of $Λ$ and $Λ ˉ$ hyperons inside jets in $pp$ collisions at $s = 200$ GeV

STAR Collaboration, B. E. Aboona, J. Adam +363

A surprisingly large transverse polarization of $Λ$ hyperons in unpolarized hadron-nucleon/nucleus collisions has been observed for 50 years, and the origin of this polarization re…

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…
