Hello,
In my understanding, decay of quarks should give leptons of the same generation as the quark has, like in a basic way, neutron decaying into proton and an electron. Because of this I have trouble understanding why the strange quark turns directy into up quark, an electron and an electron neutrino in the decay of omega baryon. Why doesnt the strange quark decay give off a muon and a muon neutrino instead of electron and electron neutrino?

Why?
They don't even couple to each other.

It does not, the decay is mediated via a W. There is no relation between quark generations and lepton generations.

The neutron cannot decay to proton+muon as there is not enough energy for the muon production. Otherwise that would be a possible decay.

I understand, thank you
