BLOOMINGTON, Ind. -- The first physics results from the upgraded Belle II experiment, the search for a new Z' vector boson "portal" into dark matter, were recently published (Editor's feature/suggested) in Physical Review Letters.
The Belle II experiment is a particle physics experiment at the intensity frontier designed to search for new physics phenomena that cannot be explained by the particles and forces already included in the Standard Model—the world’s reigning (and well-tested) theory of particle physics—while also making precision measurements of known phenomena. The Belle II world-wide collaboration is studying the properties of B mesons (heavy particles containing a bottom quark) and additionally expects significant impact from its exploration of lepton universality violation, new CP violation phases, precision electroweak measurements and dark sector physics.
