Symbol: c
Group: fermion, quark
Rest mass: 1.36 u
Diameter: 0
Charge: +2/3 e
Mean lifetime: 1.1 x 10-12 sec
Spin: 1/2
Generation: 2
Charm quarks are not stable and quickly decay, mostly to strange quarks and W+ bosons. In their short lifetime, they are part of some baryons and mesons, like the D meson.
