WebQuarks, que compõem partículas compostas como nêutrons e prótons, vêm em seis “sabores” – up, down, estranho, charmoso, top e bottom – que dão às partículas compostas suas propriedades. A interação fraca é a única que permite aos quarks trocarem seus sabores. A troca dessas propriedades é mediada pelos bósons portadores de força.
The down quark or d quark (symbol: d) is the second-lightest of all quarks, a type of elementary particle, and a major constituent of matter. Together with the up quark, it forms the neutrons (one up quark, two down quarks) and protons (two up quarks, one down quark) of atomic nuclei.
