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-…

Identified charged hadron production in Au+Au collisions at $s_{NN}$ = 54.4 GeV with the STAR detector

STAR Collaboration, B. E. Aboona, J. Adam +360

We present results on the production of $I ¨ ^{\pm}$ , $K^{\pm}$ , $p$ , and $p ˉ$ in Au+Au collisions at $s_{NN}$ = 54.4~GeV using the STAR detector at RHIC, at midra…

Measurement of transverse polarization of $I^$ and $I^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 $I^$ hyperons in unpolarized hadron-nucleon/nucleus collisions has been observed for 50 years, and the origin of this polarization r…
