Brookhaven's RHIC Ends 25-Year Run, Paving the Way for the Electron-Ion Collider

Brookhaven Lab’s Relativistic Heavy Ion Collider wraps up a 25-year run with its largest-ever dataset from heavy-ion collisions, advancing understanding of quark-gluon plasma and proton spin while laying groundwork for the future Electron-Ion Collider; the article also rounds up related HPC/AI/quantum news, including Capgemini’s Google Cloud sovereign AI partnership, ACCESS crop-trade modeling, ETH Zurich’s lattice-surgery quantum work, ISC 2026’s EESP workshop, and Quobly’s Canadian subsidiary expansion.

The Universe's Transformative Shift: Neutron Decay and Currents.

Physicists at the Relativistic Heavy Ion Collider (RHIC) are studying phase changes in nuclear matter from gold ion collisions to identify a critical point in these transformations. Their research, involving recreating and examining the transition of quark-gluon plasma, a state of matter present after the Big Bang, suggests that fluctuations in the formation of lightweight nuclei could indicate this critical point. Certain data deviations hint at potential fluctuations, but further research is required to confirm a discovery.

Positive gluon polarization indicated by direct photons.

A new publication by the PHENIX Collaboration at the Relativistic Heavy Ion Collider (RHIC) provides definitive evidence that gluon "spins" are aligned in the same direction as the spin of the proton they're in. The result provides theorists with new input for calculating how much gluons contribute to a proton's spin. The new PHENIX result is one of the "golden" measurements proposed as a key motivator for the RHIC spin physics program. It's a comparison of the number of "direct photons" (particles of light) emitted when RHIC collides protons with their spins pointing in opposite directions with the number of direct photons produced when the protons in the two beams are pointing in the same direction.

Insights into Primordial Matter Phase Changes through Hypernuclei Flow Observations

Physicists at the Relativistic Heavy Ion Collider (RHIC) have observed the directed flow of hypernuclei, rare nuclei containing at least one hyperon, in particle collisions. Hyperons, which contain a “strange” quark, are believed to be abundant in neutron stars. By simulating these conditions in the laboratory, researchers aim to understand the interactions between hyperons and nucleons. The observations, mirroring regular nuclei flow patterns, will help enhance theoretical models of neutron stars.

New insights into hypernuclei flow at RHIC from first measurements.

Physicists at the Relativistic Heavy Ion Collider (RHIC) have observed the directed flow of hypernuclei, which contain at least one "hyperon" in addition to ordinary protons and neutrons. These hyperons contain at least one "strange" quark and are thought to be abundant in the hearts of neutron stars. By comparing the flow of hypernuclei with that of similar ordinary nuclei made only of nucleons, scientists hope to gain insight into interactions between the hyperons and nucleons and understand the inner structure of neutron stars.
