All quarks are described in a similar way by electroweak and quantum chromodynamics, but the bottom quark has exceptionally low rates of transition to lower-mass quarks. The bottom quark is also notable because it is a product in almost all top quark decays, and is a frequent decay produ…

According to the Standard Model of particle physics, particles such as beauty quarks should decay into either muons or electrons in equal measure.
WebBottomness : The number of bottom (b) quarks (an anti-bottom quark counts as negative). Topness : The number of top (t) quarks (an anti-top quark counts as negative). These rules come from the underlying notion that particles emerge from the vacuum in pairs (a particle and an antiparticle).
WebThe charm and strange quark are second generation quarks — up-type and down-type, respectively. Their properties are very nearly mirrored with either the first and third generation quarks. So the charm is very similar to the up or top, while the strange is similar to the down or bottom.
