Considering the decay of certain exotic mesons, such as the following:
[tex]B^{+} --> D^{0} \pi^{+}[/tex]
Apparently the decay proceeds via a weak interaction where multiple W boson exchanges occur.
I was trying to nut out how this actually occurs, and draw up a sensible Feynman diagram representation of the process, but i can't quite nut it out.
Recall that the B+ meson is comprised of a u and anti-b quark, and the D0 is a c and anti-up, and the Pi+ is an up and anti-down, FYR.
Could someone offer me any pointers as to how such decay process usually work? First-order weak process such as beta decay are pretty straightforward, but this idea seems a bit more tricky.
