# Kaon Decay watch

1. Okay. How on earth are we expected to know the answer to this
Complete the equation for K- decay:

K- = .... + .... + ....

Is this something we're supposed to know or is it something that you can somehow derive? I know a few equations for K- decay but none of them match the Mark Scheme... The answer is a neutral pion + electron + anti neutrino....how do you get that :/ THe spec says i need to know that "kaons decay into pions" Theres like a bunch of those Kaon decay equations.. The accepted answers are pi0, e-, electron antineutrino OR pi0, mu- muon antineutrino.
