There is a pattern of these quark decays: a quark of charge +2/3 ( u,c,t) is always transformed to a quark of charge -1/3 (d,s,b) and vice versa. This is because the transformation proceeds by the exchange of charged W bosons, which must change the charge by one unit. The general pattern is that the quarks will decay to the most massive quark ...

For example, three strange quarks exist: a red strange quark, a green strange quark, and a blue strange quark. Antiquarks have anticolor. student aptjoel embiid height weight Aug 20, 2015 · The Standard Model predicted 6 types of quarks: up, down, top, bottom, charm, and strange. They are differentiated based on properties such as mass and charge. The last to be experimentally confirmed was the heaviest, the top quark. Having confirmed the existence of each type of quark, attention turned to combinations of quarks. However, the 4 heavier quarks (charm, strange, top, and bottom) can undergo decay in which they transform into lighter quarks via something called the weak interaction or weak force. Particles naturally tend to the lowest energy state, and heavier particles have higher energy, so this happens pretty fast.
