The Bottom Quark

Symbol: b Group: fermion, quark Rest mass: 4.51 u Diameter: 0 Charge: -1/3 e Mean lifetime: 1.3 x 10-12 sec Spin: 1/2 Generation: 3 |
Bottom quarks (also called beauty quarks) are not stable and quickly decay, mostly to charm quarks and W- bosons. In their short lifetime, they are part of some baryons and mesons. Due to their high mass, bottom quarks are relatively easy to research in experiments, a bottom quark is slightly heavier than a helium atom. |
