Oddball ‘neutral electron’ possibly discovered in new state of matter

A previously unknown quantum particle — equivalent to a neutral electron — may have been found in a new state of matter. The chargeless oddball wouldn’t be one of the fundamental building blocks of matter, however. Rather, it would be a quasiparticle that emerges from the collective behavior of a material only when conditions are […]

Researchers say they may have found proof of theorized axions, and possibly dark matter, around group of neutron stars — ScienceDaily

A new study, led by a theoretical physicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), suggests that never-before-observed particles called axions may be the source of unexplained, high-energy X-ray emissions surrounding a group of neutron stars. First theorized in the 1970s as part of a solution to a fundamental particle […]
