== Naming == According to [[Sheldon Glashow]], the charm quark received its name because of the "symmetry it brought to the subnuclear world".{{sfn|Glashow|1976}}{{sfn|Riordan|1987|p=[https://archive.org/details/huntingofquarktr00mich/page/210 210]}} Glashow also justified the name as "a magical device to avert evil", because adding the charm quark would prohibit unwanted and unseen decays in the three-quark theory at the time.{{sfn|Glashow|1976}} The charm quark is also called the "charmed quark" in both academic and non-academic contexts.{{sfn|Harari|1977|p=6}}{{sfn|Riordan|1992|p=1292}}{{sfn|Levine|2017}} The symbol of the charm quark is "c".{{sfn|Workman et al.|2022|p=32}}
