“Technically, these are referred to as isospin-1 / 2 bosons, but theoretically there is little difference between spin and isospin, "explains RIKEN's Akira Furusaki who, along with Konstantin Matveev from Argonne, built the theory to describe how such particles interact1.”
“We can quantify them without significantly affecting the fermions and isospin quantum numbers.”

“Are the x, y, and z axes only an isospin basis, or do they have actual directions in a physical frame?”
“The other rules may be briefly mentioned here: the weak isospin rule, the strong (color) charge rule, the mass rule, the equivalence rule, the antiparticle rule, the helicity rule and the”
“Furthermore, by the Spin Rule, the spin of the Higgs boson is 0; by the Electric Charge Rule, its electric charge is 0, by the Weak Isospin Rule, its weak isospin is 0; and by the Strong Charge Rule, its strong charge is neutral with Nc = 1.”
“U (1) generator "Y" (hypercharge) and the third, z-rotation generator of the "isospin" SU (2):”
