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

The STAR Collaboration

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

Study of Central Exclusive Production of $π^{+} π^{-}$ , $K^{+} K^{-}$ and $p p ˉ$ Pairs in Proton-Proton Collisions at $s = 510$ 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: $pp \to p h^{+} h^{-} p$ (where $h = π, K, p$ ) at the center-of-…
