Let's temporarily ignore spin. If 3 denotes the standard representation of SU(3), 1 the trivial rep, 8 the adjoint rep and 10 the symmetric cube then it's well-known that 3 x 3 x 3 = 1 + 8 + 8 + 10 ...
Can someone explain how isospin and hypercharge, can be used to label representations? What is the meaning of the term singlet, doublet etc in this context? In particular how can I use it to label ...
I asked the same question in mo. I think maybe here there are more physics guys to help me. I once read a statement (not memorized precisely) that a certain physics quantity between two states of ...
This is a question that has been posted at many different forums, I thought maybe someone here would have a better or more conceptual answer than I have seen before: Why do physicists care about ...
