analyse with respecto to quark content

[rayman123]

1. The problem statement, all variables and given/known data
I have a reaction
\Omega^{-}(sss)\rightarrow\Lambda^{0}(uds)+K^{-}(\bar{u}s) I am supposed to analyse the reaction according to the quark content
and I have connected u with \bar{u}, 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?

[rayman123]

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

I have never seen transformation such as
s\righarrow d+??? 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?

[rayman123]

nope, we only talked about the boson W.
