The flavor of quark that has a charge of −1/3, has a mass about 8,220 times that of an electron, and belongs to the third generation of elementary fermions.

CONT

Bottom 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.
