Meaning and Definition
A historical term for a now-obsolete classification of an unstable elementary particle, the muon.
In mid-20th century physics, it referred to what was then considered a type of meson, but later reclassified as a lepton (the muon) because it does not interact via the strong nuclear force.
Dialectal Variation

Common Mistakes When Using “mu meson”
- Using 'mu meson' in contemporary scientific writing instead of 'muon'.

- Pronouncing 'meson' as /ˈmɛsən/ instead of /ˈmiːzɒn/.
FAQ
Frequently Asked Questions
Yes, 'mu meson' is the historical name for what is now exclusively called the muon. The name changed when its properties were better understood.
Because its mass was measured to be between that of the electron and the proton, which was the defining characteristic of mesons at the time. It was later found not to interact via the strong force, disqualifying it from the meson family.
Primarily in historical physics texts, older textbooks, or in educational discussions about the history and development of the Standard Model of particle physics.
Always use 'muon' in any contemporary scientific or general writing. Use 'mu meson' only when deliberately referring to the historical context or quoting older sources.
