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. |
