Evidence of Spin-Interference Effects in Exclusive Photoproduction in Ultraperipheral Heavy-Ion Collisions

The STAR Collaboration

We report the first evidence of spin interference in exclusive photoproduction in ultraperipheral heavy-ion collisions at STAR at ~GeV. In Au+…

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…

Energy Independence of the Collins Asymmetry in Collisions

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

The STAR experiment reports new, high-precision measurements of the transverse single-spin asymmetries for within jets, namely the Collins asymmetries, from transversely…

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…

Tracking the baryon number with nuclear collisions

STAR Collaboration

Baryon quantum number is believed to be conserved since baryogenesis in the early Universe. While fractionally charged valence quarks are understood conventionally to each carry a…

Reaction plane correlated triangular flow in Au+Au collisions at GeV

STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +349

We measure triangular flow relative to the reaction plane at 3 GeV center-of-mass energy in Au+Au collisions at the BNL Relativistic Heavy Ion Collider. A significant signal…
