An international team has initiated the MACE experiment to detect a rare transformation of muonium into its antimatter counterpart, antimuonium. This process, if observed, would challenge the Standard Model of particle physics by violating lepton flavor conservation. The project aims to vastly improve upon previous searches conducted over two decades ago.

Scientists at Fermilab's MicroBooNE experiment have determined that the long-hypothesized sterile neutrino does not exist, based on high-precision measurements of neutrino behavior. The findings, published in Nature, show neutrinos acting as expected without evidence of a fourth type, closing a decades-old theory. This result paves the way for new investigations and advanced experiments like DUNE.
Researchers have made progress in identifying a critical point where the strong nuclear force weakens, allowing quarks and gluons to form a hot plasma. By analyzing collisions at a New York particle accelerator, scientists have narrowed the possible location of this point on a phase diagram. This finding could reveal insights into the early universe and neutron stars.

Researchers have announced a breakthrough in detecting elusive dark matter particles using advanced collider technology. The discovery, detailed in a recent Nature publication, could reshape our understanding of cosmic composition. Led by a team at CERN, the method promises more precise measurements than previous attempts.
