Hello,
I was looking at the quark masses and had this doubt regarding the muon decay: Why can't the muon decay into up and down quarks (plus neutrino). I know the explanation is because muon doesn't exhibit hadronic decays because its mass isn't big enough [itex]m_\mu=107MEV[/itex]. But I just saw that the up and down quark masses are [itex]m_u=2.4MEV[/itex] and [itex]m_d=4.8MEV[/itex]. Being much smaller than the mass of the muon, why isn't this hadronic decay possible.
Thanks
