Hi All(adsbygoogle = window.adsbygoogle || []).push({});

Thanks for welcoming me to the physics forum. I am reading Greiner and Mueller's Quantum Mechanics: Symmetries and am stuck at not understanding the vector meson ( rho meson)'s spin states.

For S=1 we get three states -1, 0, and 1.

Prof. Mueller separated them as a rho +/-1, and rho 0 .

for the rho +/-1 he mentions the state u ( spin up , spin down) *d_ (read "d bar" for anti d) ( spin up , spin down)

How did he get to this? I did the Clebsch Gordan analysis and got lost . Need some help here.

Thanks

Dwight
