The Strange Quark
|
Symbol: s Group: fermion, quark Rest mass: 0.0752 - 0.1396 u Diameter: 0 Charge: -1/3 e Mean lifetime: 1.24 x 10-8 sec Spin: 1/2 Generation: 2 |
Strange quarks normally aren't stable and quickly decay into up quarks and W--bosons. In their short lifetime, they are part of some baryons and mesons, like the kaon. Particles with a strange quark have a strangeness value of -1. Those form the strange matter. From a mass of 1000 u upwards there could be stable strange matter. This could be formed in heavy neutron stars. |
