elementary particles

Researchers have built a model according to which the mass of the Higgs boson, which helps produce the mass of elementary particles, changed in the early universe, and is therefore much smaller than the standard model of particle physics describes
Led by researchers from the Institute of Physics at Princeton University, an initial discovery has been published that strengthens the controversial hypothesis that the electron is made up of two elementary particles: one carries a negative electric charge and the other the electron's spin. If the interpretation is indeed correct, the assumption that is more than a century old may be erased and make waves in the scientific community.
