2. Baryon number - Wikipedia

   en.wikipedia.org/wiki/Baryon_number

   Three antiquarks of different anticolors, giving an antibaryon with baryon number −1. The baryon number was defined long before the quark model was established, so rather than changing the definitions, particle physicists simply gave quarks one third the baryon number. Nowadays it might be more accurate to speak of the conservation of quark ...

3. List of baryons - Wikipedia

   en.wikipedia.org/wiki/List_of_baryons

   These lists detail all known and predicted baryons in total angular momentum J = ⁠ 1 / 2 ⁠ and J = ⁠ 3 / 2 ⁠ configurations with positive parity. [5]Baryons composed of one type of quark (uuu, ddd, ...) can exist in J = ⁠ 3 / 2 ⁠ configuration, but J = ⁠ 1 / 2 ⁠ is forbidden by the Pauli exclusion principle.

4. Quark model - Wikipedia

   en.wikipedia.org/wiki/Quark_model

   Mesons are made of a valence quark–antiquark pair (thus have a baryon number of 0), while baryons are made of three quarks (thus have a baryon number of 1). This article discusses the quark model for the up, down, and strange flavors of quark (which form an approximate flavor SU(3) symmetry). There are generalizations to larger number of flavors.

5. List of mesons - Wikipedia

   en.wikipedia.org/wiki/List_of_mesons

   Mesons named with the letter "f" are scalar mesons (as opposed to a pseudo-scalar meson), and mesons named with the letter "a" are axial-vector mesons (as opposed to an ordinary vector meson) a.k.a. an isoscalar vector meson, while the letters "b" and "h" refer to axial-vector mesons with positive parity, negative C-parity, and quantum numbers I G of 1 + and 0 − respectively.

6. Meson - Wikipedia

   en.wikipedia.org/wiki/Meson

   Because quarks have a spin ⁠ 1 / 2 ⁠, the difference in quark number between mesons and baryons results in conventional two-quark mesons being bosons, whereas baryons are fermions. Each type of meson has a corresponding antiparticle (antimeson) in which quarks are replaced by their corresponding antiquarks and vice versa.

7. Baryon - Wikipedia

   en.wikipedia.org/wiki/Baryon

   In particle physics, a baryon is a type of composite subatomic particle that contains an odd number of valence quarks, conventionally three. [1] Protons and neutrons are examples of baryons; because baryons are composed of quarks, they belong to the hadron family of particles. Baryons are also classified as fermions because they have half ...

   YouTube TV and Paramount have agreed to a short-term deal extension to avoid a blackout of CBS, YouTube announced late Thursday. Paramount wanted a rate hike. Their existing deal expired at 1 p.m ...

9. Hadron - Wikipedia

   en.wikipedia.org/wiki/Hadron

   These include glueballs and hybrid mesons (mesons bound by excited gluons). Because mesons have an even number of quarks, they are also all bosons, with integer spin, i.e., 0, +1, or −1. They have baryon number B = ⁠ 1 / 3 ⁠ − ⁠ 1 / 3 ⁠ = 0 . Examples of mesons commonly produced in particle physics experiments include pions and kaons.
