The first measurement to track both the energy and the momentum transfer of near-miss lead collisions shows a three-sigma suppression at the smallest scales. It fits gluon saturation, a prediction that has waited decades for a clean test.
Physicists thought only heavy nuclei like lead could produce quark-gluon plasma. The ALICE collaboration just made it with nuclei a fraction of the size, which means the recipe is not what anyone assumed.
Laser spectroscopy on fermium-255 shows a nucleus stretched like a rugby ball — and produced a magnetic moment that contradicts the published value.
Fudan University physicists mapped acceleration inside quark-gluon plasma for the first time and found it peaks at several hundred MeV along the fireball's edge — enough, through the Unruh effect, to mimic the temperature at which matter changes state.
Researchers at 25 institutions showed the mysterious 'low-energy enhancement' comes from magnetic transitions inside the nucleus — a result that changes how fast stars are calculated to build heavy elements.
Physicists at TU Darmstadt recalculated the masses of 70 exotic nuclei and found the traffic jam that builds heavy elements in neutron star collisions lasts longer than every previous model assumed.
Lawrence Livermore researchers recreate extreme conditions using plasma flow reactor, revealing how cooling patterns dramatically alter radioactive particle formation.
Lawrence Livermore researchers recreate intense chaos inside nuclear explosions, revealing how cooling rate dramatically changes radioactive particle formation.
Lawrence Livermore researchers used plasma flow reactor to simulate post-detonation environment, revealing how cooling rates dramatically alter radioactive particle formation. Findings could improve nuclear event analysis and safety models.
Lawrence Livermore researchers found that the cooling process dramatically changes radioactive particle formation, especially for volatile elements like cesium.
Breakthrough experiment reveals evidence of strange new matter state where fleeting particles get trapped inside atomic nuclei, potentially solving fundamental questions about how particles acquire mass.
Breakthrough experiment measures key reaction creating selenium-74, shedding new light on supernova nucleosynthesis while revealing gaps in current theories.
Breakthrough experiment directly measured how arsenic-73 captures protons to form selenium-74, shedding new light on the mysterious origin of proton-rich elements in supernovas.
Breakthrough experiment directly measures key nuclear process that creates selenium-74 in supernova explosions, cutting uncertainty in stellar models by half.
A 45-scientist team at Michigan State's FRIB measured the arsenic-73 + proton reaction that occurs inside supernovae, cutting uncertainty in p-nuclei abundance predictions by 50% and advancing a 60-year-old astrophysics mystery.
A new technique using grazing-angle particle interactions allows physicists to directly measure how gluons behave under extreme nuclear density — the particles that literally hold the universe together.
Scientists discover that stellar rotation dramatically boosts element transport in aging stars, explaining long-observed chemical changes at their surfaces.
