This is the first known particle with four of the same kind of quark
In a never-before-seen particle, four quarks of a feather flock together. Physicists think they have detected the first conglomerate of four quarks incorporating more than two of the same kind.…
Physicists spot a new class of neutrinos from the sun
Neutrinos spit out by the main processes that power the sun are finally accounted for, physicists report. Two sets of nuclear fusion reactions predominate in the sun’s core and both…
An unexpected result from a dark matter experiment may signal new particles
An experiment searching for cosmic dark matter may have finally detected something. But it’s not dark matter. Scientists with the XENON1T experiment reported data June 17 showing an unexpectedly large…
Measuring the neutron’s lifetime from space could solve an enduring mystery
To really understand neutrons, physicists may have to take to space. When outside the confines of an atomic nucleus, a neutron decays into other particles in about 15 minutes on…
A star shredded by a black hole may have spit out an extremely energetic neutrino
A neutrino that plowed into the Antarctic ice offers up a cautionary message: Don’t stray too close to the edge of an abyss. The subatomic particle may have been blasted…
A controversial X-ray glow didn’t show up in the Milky Way’s dark matter halo
Glowing X-rays around distant galaxies can’t come from dark matter particles, new research shows. The mysterious glow failed to show up in the dark matter halo around the Milky Way,…
Particles called axions could reveal how matter conquered the universe
Chalk up a potential third win for hypothetical particles called axions. If the subatomic particles exist, they could solve two pressing puzzles of particle physics: the source of the dark…
Physicists have narrowed the mass range for hypothetical dark matter axions
Bit by bit, physicists are winnowing down the potential masses for hypothetical particles called axions. If they exist, the subatomic particles could make up dark matter, a mysterious source of…
