Nuclear & Particle Physics - Muon

Except for mass, the properties of the muon most closely resemble the properties of the

A. electron
B. graviton
C. photon
D. pion
E. proton

(GR8677 #16)

Solution:

(A) TRUE
Muon and electron are elementary particles → fermions (half-integer spin) → leptons (one unit charge)

(B) FALSE
Graviton is gravity force carrier → boson (integer spin)

(C) FALSE
Photon is EM force carrier → boson (integer spin)

(D) FALSE
Pion is composite particle → meson (consist of quark-antiquark)

(E) FALSE
Proton is composite particle → baryon (consist of 3 quarks)
