Bosons

A collaboration of physicists has made the most precise measurement of the mass of the W boson. The new measurement of this key particle differs drastically from the Standard Model's predictions– and it may unravel physics as we know it.

A huge range of dark matter suspects are being investigated. In a new study, astronomers have searched for clouds of hypothetical ultralight particles that could congregate around black holes, and reveal themselves by sending out gravitational waves.

With elusive dark matter continuing to evade detection, scientists are having to search in stranger and stranger places. In a new study, physicists at MIT have studied the spins of black holes for signs of drag from dark matter slowing them down.

Last year gravitational waves were detected from a massive black hole collision. But now astrophysicists propose a new explanation: a collision of two boson stars – hypothetical, invisible objects that could help untangle the mystery of dark matter.

Physicists have discovered a new form of matter called excitonium. First theorized almost 50 years ago, the Illinois researchers have found a “smoking gun” that they claim is the first definitive proof that excitonium exists.

​Glueballs are long sought-after exotic particles, created from pure force. Researchers at TU Wien claim to have discovered this mysterious particle in the remnants of collisions in particle accelerators.

An exotic particle dubbed the "Weyl fermion", has been discovered 85 years after its existence was first mooted. Able to create completely massless electrons, the use of this particle may result in super-fast electronics and significant inroads into new areas of quantum computing.

Researchers working at Massachusetts Institute of Technology (MIT) claim to have created a microscope able to image fermions; the fundamental particles that make up all matter in the universe.

Discovery of an elementary particle not predicted by the Standard Model of Particle Physics has been reported and confirmed.
