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-…

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…

Onset of Constituent Quark Number Scaling in Heavy-Ion Collisions at RHIC

STAR Collaboration, B. E. Aboona, J. Adam +355

Partonic collectivity is one of the necessary signatures for the formation of quark-gluon plasma in high-energy nuclear collisions. Number of constituent quarks (NCQ) scaling has b…

Imaging Shapes of Atomic Nuclei in High-Energy Nuclear Collisions

STAR Collaboration

Atomic nuclei are self-organized, many-body quantum systems bound by strong nuclear forces within femtometer-scale space. These complex systems manifest a variety of shapes, tradit…

Measurement of flow coefficients in high-multiplicity $p$ +Au, $d$ +Au and $^{3}$ He $+$ Au collisions at $s_{_{NN}}$ =200 GeV

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +350

Flow coefficients ( $v_{2}$ and $v_{3}$ ) are measured in high-multiplicity $p$ +Au, $d$ +Au, and $^{3}$ He $+$ Au collisions at a center-of-mass energy of $s_{_{NN}}$ = 200 G…
