I was wondering if there was something similar to the 8 fold way representation used on mesons for the fermions?
tom.stoer said:of course
there is are two triangle-diagrams for the two fundamental triplet (quark and antiquark) representations of SU(3) http://universe-review.ca/I15-38-8foldway.jpg
and there are the baryon octet and decuplet diagrams http://en.wikipedia.org/wiki/Eightfold_Way_(physics )
assuming you are talking about 3 flavours, otherwise it becomes more complex (e.g. for 4 flavours) http://static.wix.com/media/d3fcbc01ff7f7e88aceb6487fcd99333.wix_mp
The 8 fold way is a representation diagram used in particle physics to classify mesons, which are subatomic particles made of a quark and an antiquark. This diagram shows the relationship between different types of mesons based on their quantum numbers.
Fermions are a type of subatomic particle that have half-integer spin, such as electrons, protons, and neutrons. They follow the Pauli exclusion principle, which states that no two fermions can occupy the same quantum state simultaneously.
While there is no specific representation diagram for fermions like the 8 fold way for mesons, there are other ways to classify and visualize fermions. For example, the Standard Model of particle physics uses a representation called the quark-lepton diagram, which shows the relationship between different types of fermions based on their properties.
Fermions and mesons have different properties and behaviors. Fermions are fundamental particles, while mesons are composite particles. Fermions have half-integer spin, while mesons have integer spin. Additionally, fermions are subject to the Pauli exclusion principle, while mesons are not.
Yes, there are some particles that do not fit into the 8 fold way for mesons, such as the pentaquark. This particle is made of five quarks and does not follow the same classification as other mesons. Additionally, the 8 fold way is based on the quark model, which has since been expanded to include other particles and interactions.
