![]() What does lepton mean Proper usage and audio pronunciation of the word. These are the charged electrons but have more mass. ![]() They appear like point-like particles that don’t have internal structures. There are six leptons, three of them have an electrical charge and three do not. There are other technical answers 'leptons are the particles that carry lepton number', but they are kind of useless. A lepton is an elementary half-integer spin particle that does not get involved in strong interactions. photons are neither leptons nor baryons (which are both fermions), but are bosons. In recent years these processes have attracted a lot of attention, in part due to several experimental measurements defying theoretical expectations within the SM. Definition of lepton (lepta) in the Dictionary. Leptons are spin 1/2 particles that interact via the electroweak force but not the strong force. Consequently they constitute powerful probes of possible flavor dynamics beyond the SM. ![]() Rare (semi)leptonic b-hadron decays allow for some of the most sensitive tests of the standard model (SM) description of flavor. Leptons participate in weak interactions, but not strong interactions, and have masses generally less than those of mesons and baryons. a small brass coin, equivalent to the eighth part of an 'as', worth about a 1/5 of a cent.
