The Decay Example
Is the decay example correct? The discussion of Kaon oscillations (https://en.wikipedia.org/wiki/Kaon#Oscillation) tells us that the K0 decays to positrons in semileptonic decays, while the K0-bar decays to electrons. That seems correct:
In the quark model, the K0 is d s-bar, and the s-bar decays to u-bar which, combined with the d, gives a pi-. Charge conservation requires the lepton to be a positron rather than an electron.

Because of past experience, I lack sufficient confidence to correct the reaction myself. Johnm307 (talk) 09:33, 17 March 2022 (UTC)
