I have a basic question about pseudoscalar mesons wavefunction.
As I understand it, mesons are bosons so they have a total symmetric wavefunction under exchange of particles.
For pseudoscalar mesons, the spacial wavefunction is anti-symmetric because the parity is negative ($P=(-1)^{L+1}$ and $L=0$ ).
The spin wavefunction is antisymmetric because it's in the singlet state.
The Color wavefunction is symmetric for all mesons.
That leaves me with the flavor wavefunction - for the octet particles, the flavor seems anti-symmetric, and the total wave function is antisymmetric.
How is it possible ?
