The D Meson

Symbol: D
Group: boson, hadron, meson
Rest mass: 2.11 u
Charge: -1, 0, +1
Mean lifetime: 0.5 - 1 x 10-12 sec
Spin: 0 or 1
D mesons are particles made of a charm and a lighter antiquark or an anticharm and a lighter quark. They are short-lived and decay in multiple ways, which makes them an interesting object of research.
