(Phys.org) —A trio of researchers from Germany, Bulgaria and Russia has proposed the idea of using a molecular clock to determine if the electron-proton mass ratio changes over time. In their paper published in Physical ...
The NEMO (Neutrino Ettore Majorana Observatory) experiment, whose goal was to elucidate the nature of neutrinos and measure their mass, yielded very positive results. The product of an extensive international collaboration ...
