The team of physicists working on the LHCb Collaboration at CERN has found that bottom quarks are more likely to exist in baryons than mesons as the density of the environment in which they exist increases. In their paper ...
The LHCb collaboration recently reported on the arXiv preprint server the first observation of the decay of the Bc+ meson (composed of two heavy quarks, b and c) into a J/ψ charm-anticharm quark bound state and a pair of ...
Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
A study led by Prof. Chen Xurong at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has provided new insights into the origins of proton mass. From an experimental standpoint, the researchers ...
Scientists are getting a more detailed look than ever before at the electrons they use in precision experiments.
A new analysis by the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, provides the first direct evidence of the ...
Neutron stars in the universe, ultracold atomic gases in the laboratory, and the quark–gluon plasma created in collisions of atomic nuclei at the Large Hadron Collider (LHC): they may seem totally unrelated but, surprisingly ...
Since the 1960s, scientists have discovered more than a dozen fundamental particles. They all have fit perfectly into the theoretical framework known as the Standard Model, the best description physicists have of the subatomic ...
A team of astronomers has found that the total mass of stars in a galaxy is not a good predictor of the galaxy's abundance of heavier elements, a surprising result according to previous studies. Instead, the gravitational ...
Collisions of high energy particles produce "jets" of quarks, anti-quarks, or gluons. Due to the phenomenon called confinement, scientists cannot directly detect quarks. Instead, the quarks from these collisions fragment ...
