2 configurations. Two J = 1. 2 configurations are possible for these baryons. The symbols encountered in these lists are: I ( isospin ), J ( total angular momentum ), P ( parity ), u ( up quark ), d ( down quark ), s ( strange quark ), c ( charm quark ), b ( bottom quark ), Q ( charge ), B ( baryon number ), S ( strangeness ), C ( charm ), B ...
List of mesons. ) is a process that involves both weak and strong interactions. ). ). This list is of all known and predicted scalar, pseudoscalar and vector mesons. See list of particles for a more detailed list of particles found in particle physics. This article contains a list of mesons, unstable subatomic particles composed of one quark ...
Top quark. The top quark, sometimes also referred to as the truth quark, (symbol: t) is the most massive of all observed elementary particles. It derives its mass from its coupling to the Higgs Boson. This coupling is very close to unity; in the Standard Model of particle physics, it is the largest (strongest) coupling at the scale of the weak ...
ダウンクォーク (down quark, 記号:d) は、物質を構成する主要な素粒子の一つで、第一世代のクォークである。 概要. ダウンクォークは、二番目に軽いクォークであり、 -1/3e の電荷を持ち、裸の質量は 4～8 MeVである。
Strange quark. The strange quark or s quark (from its symbol, s) is the third lightest of all quarks, a type of elementary particle. Strange quarks are found in subatomic particles called hadrons. Examples of hadrons containing strange quarks include kaons (. ), and other strange particles . According to the IUPAP, the symbol s is the official ...
The up quark or u quark (symbol: u) is the lightest of all quarks, a type of elementary particle, and a significant constituent of matter. It, along with the down quark, 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 ...
Flavour inparticle physics. In nuclear physics and particle physics, isospin ( I) is a quantum number related to the up- and down quark content of the particle. Isospin is also known as isobaric spin or isotopic spin . Isospin symmetry is a subset of the flavour symmetry seen more broadly in the interactions of baryons and mesons .
