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 +378

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-…

Energy Independence of the Collins Asymmetry in $p^{↑} p$ Collisions

STAR Collaboration, B. E. Aboona, J. Adam +367

The STAR experiment reports new, high-precision measurements of the transverse single-spin asymmetries for $π^{\pm}$ within jets, namely the Collins asymmetries, from transversely…

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…
