hi,
is the following decay possible?
[tex]\pi^- \rightarrow u \bar{u} + \mu^- + \bar{\nu}_\mu[/tex]
my idea: the quark content of [tex]\pi^-[/tex] is [tex]\bar u d[/tex] , the d quark could decay into an up-quark, emitting a [tex]w^-[/tex] boson which decays into the muon and anti-muon-neutrino.
or is there any problem?
(normally, you only see this decay: [tex]\pi^- \rightarrow \mu^- + \bar{\nu}_\mu[/tex] listed)
