Homework Statement


I have a reaction
[tex] \Omega^{-}(sss)\rightarrow\Lambda^{0}(uds)+K^{-}(\bar{u}s)[/tex] I am supposed to analyse the reaction according to the quark content
and I have connected u with [tex] \bar{u}[/tex], s with s, another s with s and I am left with s and d......how can I solve this?
there can not be transistion between s into d......

there can not be transistion between s into d.
Why not?

in my book there are only following transistions showed (I thought they were the only possible ones)
[tex] u\rightarrow d+W^{+}[/tex]
[tex]\bar{u}\rightarrow\bar{d}+W^{-}[/tex]
[tex]s\rightarrow\bar{u}+W^{-}[/tex]
[tex]\bar{s}\rightarrow\bar{u}+W^{+}[/tex]

I have never seen transformation such as
[tex] s\righarrow d+???[/tex] where I can find full list of available transformations? or is there a system which governs these transformations?

The weak force is mediated by two bosons, the W and the Z. Were you given any transitions involving the Z?

nope, we only talked about the boson W.
