Bottom quark - Wikipedia
WEBThe bottom quark, beauty quark, or b quark, is an elementary particle of the third generation. It is a heavy quark with a charge of − 1 3 e. All quarks are described in a similar way by electroweak interaction and quantum chromodynamics, but the bottom quark has exceptionally low rates of transition to lower-mass quarks.
What is a bottom quark? – Stephen Sekula – Physicist - SMU
WEBThe bottom quark is the second-heaviest known quark. It is a “down-type” quark, meaning that it has an electric charge that is negative and one-third that of the elementary charge of the electron (-1/3e).

WEBThe Bottom Quark. In 1977, an experimental group at Fermilab led by Leon Lederman discovered a new resonance at 9.4 GeV/c 2 which was interpreted as a bottom-antibottom quark pair and called the Upsilon meson. From this experiment, the mass of the bottom quark is implied to be about 5 GeV/c 2. The reaction being studied was
The Discovery of the Bottom Quark
WEBMar 31, 2001 · Analysis of the properties of the upsilon has confirmed that it is made from the quark-anitquark pair of a new kind of quark. This quark has been called "beauty" or "b" but is now commonly referred to as the bottom quark. Note that at 4.3 GeV, a single bottom is 4.5 times the mass of a proton.
