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.It is part of the first generation of matter, has an electric charge of − 1 / 3 e and a bare mass of 4.7 …

A strangelet (pronounced / ˈ s t r eɪ n dʒ. l ɪ t /) is a hypothetical particle consisting of a bound state of roughly equal numbers of up, down, and strange quarks.An equivalent description is that a strangelet is a small fragment of strange matter, small enough to be considered a particle.The size of an object composed of strange matter could, theoretically, range from a few …

Flavours. Die Quarks treten in sechs „Flavours“ (englisch Geschmacksrichtung, amerik.Englisch flavor) auf, genannt up (u), down (d), strange (s), charm (c), bottom (b) und top (t).Diese Flavours werden durch die Quantenzahlen Isospin (I), Strangeness (S), Charm (C), Bottomness (B′) und Topness (T) beschrieben.. Die Flavours unterscheiden sich bezüglich der Masse, der …
