On the difficulties a lonely lepton In conversions of elementary particles into each other, the total electric charge of the particles before conversion is equal to that after. If electrons, muons, tau-leptons or neutrinos are involved in the conversion, similarly … Continue reading
How it cooled down what couldn’t be hotter Immediately after the Big Bang, the universe was a hot and dense mixture of actively interacting quarks and leptons. In a second, their density and kinetic energy, i.e., their temperature dropped so … Continue reading
Some ignore the neighbors, others interact with everyone Firstly, a large group is distinguished among the particles, which is called leptons. The leptons interact very weakly with other particles. This applies particularly to the lightest lepton neutrino that, unlike others, … Continue reading
