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+…
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…
Estimate of Background Baseline and Upper Limit on the Chiral Magnetic Effect in Isobar Collisions at GeV at the Relativistic Heavy-Ion Collider
STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +342
For the search of the chiral magnetic effect (CME), STAR previously presented the results from isobar collisions (, ${^{96}_{40}\text{Z…
Upper Limit on the Chiral Magnetic Effect in Isobar Collisions at the Relativistic Heavy-Ion Collider
STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +342
The chiral magnetic effect (CME) is a phenomenon that arises from the QCD anomaly in the presence of an external magnetic field. The experimental search for its evidence has been o…
Observation of the Antimatter Hypernucleus
STAR Collaboration, M. I. Abdulhamid, B. E. Aboona +350
At the origin of the Universe, asymmetry between the amount of created matter and antimatter led to the matter-dominated Universe as we know today. The origins of this asymmetry re…
