Follow Physics & CERNA new preprint suggests that enigmatic transient star-like objects, identified in the Palomar Observatory Sky Survey (POSS-1) by the VASCO project, could be a manifestation of dark matter physics. The origin of these 'Mysterious Transients' remains unknown, and this hypothesis explores a dark matter explanation for the observed phenomena, potentially opening new avenues in fundamental physics research.
Physicists at CERN's ALICE experiment have made the most detailed measurements of gluon behavior within atomic nuclei, finding evidence for gluon saturation. This phenomenon, where gluons become densely packed and limit their numbers, was predicted by quantum chromodynamics. Published in Physical Review Letters, these results offer new insights into the fundamental structure of matter and challenge previous explanations.
Fermilab's Muon g-2 experiment has conducted the most sensitive direct search for a muon electric dipole moment (EDM), analyzing 25% of its data. The results are consistent with an EDM of zero, establishing a new upper limit 1.5 times more stringent than previous measurements. This finding helps constrain theories of new physics beyond the Standard Model, which could explain the universe's matter-antimatter asymmetry.
Physicists at CERN's ALICE experiment have conducted detailed measurements of gluon behavior within atomic nuclei, finding evidence for a densely packed state known as gluon saturation. This discovery challenges existing theories on gluon distribution and provides a clearer understanding of the hidden structure of atomic nuclei. The findings represent a significant advancement in particle physics.
The Electron-Ion Collider (EIC) project at Brookhaven National Laboratory and CERN have deepened their international scientific collaboration. A recent CERN Colloquium highlighted the EIC's mission and future opportunities, indicating growing global interest in the facility. This partnership aims to advance fundamental physics knowledge and foster new technology development.
MIT PhD student Jessica Fry is actively engaged in the search for the axion at the Laboratory for Nuclear Science. This hypothetical elementary particle is considered a leading candidate for dark matter. Her research represents a significant effort in fundamental physics, aiming to uncover one of the universe's most elusive particles and advance our understanding of cosmic composition.
