why the isospin wave function was not considered in quark model? only the others (flavour, color, space, spin) are considered?
The total wave function must be completely antisymmetric. The color part is also completely antisymmetric because baryons have zero color. Therefore, the combination of spin, flavor (which as I said includes isospin) and space must be totally symmetric.please explain some thing more than that.
and the total wave function of baryons should be anti symmetric under the exchange of particles(fermions), then the combination of spin part and flavour part should be symmetric because color part is anti symmetric and spatial part is symmetric (note! here spatial wave function is product of spin, flavour, space and color. isospin is not consider.) what about the combination of spin part and isospin part interms of particle exchane?
It sounds like whatever you were reading was considering an ##L=0## state. Since the orbital wavefunction is symmetric, then the spin-isospin part must also be symmetric in this case.a model ans said that combination of spin and isospin part should be symmetric, is that correct?
please explain me elaborately
Isospin symmetry is precisely the flavor symmetry if we restrict to the states composed of the up and down quarks. With 2 quarks we build the states from the doubletthanks a lot.
could you explain me how the isospin is related with flavour in L=0 state?
if isospin part is symmetric then what about flavour?
