Is a diquark [tex]$ [q_1q_2]$ [/tex] a totally antisymmetric state in color, flavor and spin space,(adsbygoogle = window.adsbygoogle || []).push({});

i.e. a color antitriplet [tex]$\overline{3}_c$[/tex], flavor antitriplet [tex]$\overline{3}_f$[/tex]

and spin singlet?

So if it has u, d flavors, how to write it explicitely?

[tex] $ |ud -du \rangle \otimes \frac{1}{\sqrt{N_c}}|cc> \otimes \frac{1}{\sqrt{2}}(|\uparrow\downarrow \rangle - |\downarrow\uparrow \rangle)$ [/tex] ???
