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.
flavour, in particle physics, property that distinguishes different members in the two groups of basic building blocks of matter, the quarks and the leptons. There are six flavours of subatomic particle within each of these two groups: six leptons (the electron , the muon , the tau , the electron- neutrino , the muon-neutrino, and the tau ...
In particle physics, strangeness (symbol S) [1] [2] is a property of particles, expressed as a quantum number, for describing decay of particles in strong and electromagnetic interactions which occur in a short period of time. The strangeness of a particle is defined as: where n. s. represents the number of strange quarks ( s. ) and n. s.
Since the flavour rotations A are approximate, not exact, symmetries, each orthogonal state in the vector space corresponds to a different particle species. In the example above, when a proton is transformed by every possible flavour rotation A , it turns out that it moves around an 8 dimensional vector space.
12 de mar. de 2019 · Abstract: We give a brief introduction to flavour physics. The first part covers the flavour structure of the Standard Model, how the Kobayashi-Maskawa mechanism is tested and provides examples of searches for new physics using flavour observables, such as meson mixing and rare decays.

12. There are six types of quarks, known as flavors. Why where these types called flavors?

Remark – mixing parameters are what they are because of SM (CKM, GIM & quark masses) and could easily be perturbed by New Physics, so bounds can be set. the mass scale of the New Physics. If we assuming the coupling is ~1, (i.e. generic) obtain the following → bounds on ΛNP [Nir, arXiv:1605.00433].
