Belle II experiment reports the first direct measurement of tau-to-light-lepton ratio
The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort ...
What flavor is that neutrino? Adding flavor helps to track neutrino movement in astrophysical systems
Neutrinos have a quantum mechanical property called "flavor." This flavor can transform as neutrinos move through space. A major challenge is to keep track of both the physical movement of the neutrinos and their change of ...
