Quark - Wikipedia
WEBUp, charm, and top quarks (collectively referred to as up-type quarks) have a charge of + 2 / 3 e; down, strange, and bottom quarks (down-type quarks) have a charge of − 1 / 3 e. Antiquarks have the opposite charge to their corresponding quarks; up-type antiquarks have charges of − 2 / 3 e and down-type antiquarks ...
Why are the quarks so named? - Physics Stack Exchange
WEBThe up/down top/bottom should be self evident: in a matrix representation the vector is written that way +1/2>-1/2> So in the isotopic spin space (the SU(2) of the SU(2)xSU(3)xU(1) of the Standard Model) according to the charge the one on top was called the up and the one on bottom, the down.
Subatomic particle - Quarks, Antiquarks, Gluons | Britannica
WEBJul 31, 2024 · The six varieties, or “flavours,” of quark have acquired the names up, down, charm, strange, top, and bottom. The meaning of these somewhat unusual names is not important; they have arisen for a number of reasons.
DOE Explains...Quarks and Gluons | Department of Energy
WEBThere are six different kinds of quarks with a wide range of masses. They are named up, down, charm, strange, top, and bottom. Quarks are the only elementary particles to experience all the known forces of nature and to have a fractional electric charge.
Charm quark - Wikipedia
WEBThe charm quark, charmed quark, or c quark is an elementary particle found in composite subatomic particles called hadrons such as the J/psi meson and the charmed baryons created in particle accelerator collisions. Several bosons, including the W and Z bosons and the Higgs boson, can decay into charm quarks.

Top quark - Wikipedia
WEBThe Higgs–Yukawa couplings of the up, down, charm, strange and bottom quarks are hypothesized to have small values at the extremely high energy scale of grand unification, 10 15 GeV. They increase in value at lower energy scales, at which the quark masses are generated by the Higgs.
