Subatomic particle - Quarks and antiquarks Britannica
In particle physics, flavour or flavor refers to the species of an elementary particle. The Standard Model counts six flavours of quarks and six flavours of leptons. They are conventionally parameterized with flavour quantum numbers that are assigned to all subatomic particles. They can also be described by some of the family symmetries proposed for the quark-lepton generations.

The Standard Model is the theoretical framework describing all the known elementary particles. This model contains six flavors of quarks ( q ), named up ( u ), down ( d ), strange ( s ), charm ( c ), bottom ( b ), and top ( t ). Antiparticles of quarks are called antiquarks, and are denoted by a bar over the symbol for … See more A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of See more For some time, Gell-Mann was undecided on an actual spelling for the term he intended to coin, until he found the word quark in James Joyce's 1939 book Finnegans Wake See more As described by quantum chromodynamics, the strong interaction between quarks is mediated by gluons, massless vector gauge bosons. Each gluon carries one color charge and one anticolor charge. In the standard framework of particle interactions (part of a more … See more 1. ^ There is also the theoretical possibility of more exotic phases of quark matter. 2. ^ The main evidence is based on the resonance width of the Z boson, which constrains the 4th … See more The quark model was independently proposed by physicists Murray Gell-Mann and George Zweig in 1964. The proposal came shortly after … See more Electric charge Quarks have fractional electric charge values – either (−1/3) or (+2/3) times the elementary charge (e), … See more • Physics portal • Color–flavor locking • Koide formula • Nucleon magnetic moment See more WebIsospin. In nuclear physics and particle physics, isospin ( I) is a quantum number related to the up- and down quark content of the particle. More specifically, isospin symmetry is a subset of the flavour symmetry seen more broadly in the interactions of baryons and mesons . The name of the concept contains the term spin because its quantum ... Web1 day ago · The jet charge is an old observable that has proven uniquely useful for discrimination of jets initiated by different flavors of light quarks, for example. In this Letter, we propose an approach to understanding the jet charge by establishing simple, robust assumptions that hold to good approximation nonperturbatively, such as isospin ... either way i win by frank arnold cd
