I SU(2) and SU(3) of quarks

  1. Nov 5, 2016 #1
    Hello! I am reading something related to algebra in particle physics and I want to make sure I got it. So, they say the u, d and s quarks can represent the basis of the SU(3) representation when the diagonalizable matrices are Y=B+S and ##I_3##. But, if I want to look only in the ##I_3## space (without Y), can I say that u, d and s represent the basis of a 3x3 representation of SU(2)?
    Thank you!
