CERN Quantum Technology Initiative unveils strategic roadmap shaping CERN’s role in next quantum revolution
The CERN Quantum Technology Initiative (CERN QTI) reaches its next milestone today, with the unveiling of a first roadmap defining its medium- and long-term quantum research programme. The roadmap details the CERN QTI goals and strategy, and outlines its governing structure and the composition of its international advisory board, as well as the activities to support the exchange of knowledge and innovation with the high-energy physics community and beyond in the extensive field of quantum technologies. Through CERN QTI, CERN is disseminating its enabling technologies – such as quantum state sensors, time synchronisation protocols, and many more from the cryogenics, electronics, quantum theory and computing domains – to accelerate the development of quantum technologies.

Direct Photons Offer Glimpse of Gluons' Dynamic Motion
Scientists seeking to explore the teeming microcosm of quarks and gluons inside protons and neutrons report new data delivered by particles of light. The light particles, or photons, come directly from interactions of a quark in one proton colliding with a gluon in another at the Relativistic Heavy Ion Collider (RHIC). By tracking these “direct photons,” members of RHIC’s PHENIX Collaboration say they are getting a glimpse—albeit a blurry one—of gluons’ transverse motion within the building blocks of atomic nuclei.

Dark Matter Day aims to shed light on the missing matter of the universe
We live in a universe we know surprisingly little about. The normal matter we can see—like people, planets, stars, and even peanut butter—accounts for an estimated 20 percent of all the matter in the universe. The remaining approximately 80 percent is called dark matter. We can’t see it and we don’t know what is, yet this ubiquitous substance whizzes through the universe—and us—all the time. So how do we know dark matter exists?

Professor Eliezer Rabinovici elected as next President of the CERN Council
The CERN Council has today announced the election of Professor Eliezer Rabinovici as its 24th President, for a period of one year, renewable twice, with a mandate starting on 1 January 2022. He will be taking over from Dr Ursula Bassler, who concludes her three-year term at the end of December 2021.

Physicists compared collisions of two different sets of isobars, which are ions that have the same overall mass but different numbers of protons—zirconium (96Zr), with 40 protons, and ruthenium (96Ru) with 44 protons. The higher proton number (and thus electric charge) in ruthenium should generate a stronger magnetic field during collisions than zirconium (indicated by size of gray arrows). Scientists expected the stronger magnetic field of ruthenium collisions to result in greater separation of charged particles emerging from those collisions than seen in zirconium collisions.
Results from Search for 'Chiral Magnetic Effect' at RHIC
Physicists from the STAR Collaboration of the Relativistic Heavy Ion Collider (RHIC), a U.S. Department of Energy (DOE) Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory, presented long-awaited results from a “blind analysis” of how the strength of the magnetic field generated in certain collisions affects the particles streaming out. The experiment was designed to look for evidence of a predicted physics phenomenon known as the “chiral magnetic effect.” It didn’t come out as initially predicted.

Making matter from light: Two gold (Au) ions (red) move in opposite direction at 99.995% of the speed of light (v, for velocity, = approximately c, the speed of light). As the ions pass one another without colliding, two photons (γ) from the electromagnetic cloud surrounding the ions can interact with each other to create a matter-antimatter pair: an electron (e-) and positron (e+).
Collisions of Light Produce Matter/Antimatter from Pure Energy
Scientists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC)—a U.S. Department of Energy Office of Science user facility for nuclear physics research at DOE’s Brookhaven National Laboratory—have produced definitive evidence for two physics phenomena predicted more than 80 years ago. The results were derived from a detailed analysis of more than 6,000 pairs of electrons and positrons produced in glancing particle collisions at RHIC and are published in Physical Review Letters.

Electron-Ion Collider Achieves Critical Decision 1 Approval
The U.S. Department of Energy (DOE) has granted Critical Decision 1 (CD-1) for the Electron-Ion Collider (EIC), a one-of-a-kind nuclear physics research facility to be built at DOE's Brookhaven National Laboratory on Long Island. Following DOE's approval of "mission need" (known as CD-0) in December 2019, this announcement marks the completion of the project's definition phase and its conceptual design. Approval of CD-1 provides the authorization to begin the project execution phase, starting with preliminary design.

Chasing cosmic particles with radio antennas in Greenland's ice
In Greenland's ice sheet, a set-up unlike any other in the world will in future be listening for extremely elusive particles from space. The Radio Neutrino Observatory Greenland (RNO-G) is a pioneering project that relies on a new method of detecting very high-energy cosmic neutrinos using radio antennas. The scientists involved in the project have now installed the first antenna stations in the ice at the Summit Station research facility.
