A 100-fold leap into the unknown: a new search for muonium conversion into antimuonium

The Muonium-to-Antimuonium Conversion Experiment (MACE) aims to detect the rare conversion of muonium into antimuonium, a process that could reveal new physics. The experiment seeks to improve upon the last experimental limit by more than two orders of magnitude and target a conversion probability as low as 10^-13.

Glimmers of antimatter to explain the "dark" part of the universe

A recent study suggests that the observation of antihelium nuclei in cosmic rays may be consistent with the existence of WIMP particles, which could make up dark matter. The detection of two distinct isotopes, antihelium-3 and -4, is particularly intriguing as heavier nuclei are unlikely to be produced through natural processes.

Breaking supersymmetry

Kanazawa University researcher Hajime Moriya shows that the extended Nicolai supersymmetric fermion lattice model breaks supersymmetry and has a strictly positive energy density for any homogeneous ground state. This contradicts previous claims that supersymmetry may be restored in the infinite-volume limit.

Searching high and low for dark matter

Researchers have made significant advancements in sensitivity and believe a dark matter particle interacts with ordinary matter rarely, according to conference discussions. The hunt for dark matter continues, with the LHC yet to find evidence of supersymmetry, but potential discovery could reveal dominant form of universe-seeding matter.
