bottom quark

n. Abbr. b

A quark with a charge of - ¹/₃ and a mass about 10,000 times that of the electron. Also called beauty quark. See Table at subatomic particle.

bottom quark (b

A quark with a charge of - ¹/₃ . Its mass is smaller than that of the top quark, but larger than that of all the other quarks. The bottom quark is sometimes referred to as the beauty quark, though this term is falling out of use. See Table at subatomic particle.
