Why is uds->uud+danti-up an allowed hardron reaction?

[EDerkatch]

Could someone please explain to me why uds->uud+danti-up is an allowed reaction even though individual quark number conservations are violated?

its a weak interaction, where Strangeness is not needed to be a conserved entity.

Because it's a weak interaction, which doesn't conserve flavor.

PS It's "hadron".

Yes that is true, I forgot to tell him that too ;)
