Hi all,
So I’ve been going through paper 1 I did and I think some questions were marked wrong, could anyone answer one or more of the following questions? Thanks
1. Determine whether the following reaction is possible for the neutral pion π^0
π^0->e^- + u^+ + (electron anti neutrino)
2. A student suggests that the kaon K^0 and the anti-Kaon K^0(bar on top) are the same particle, discuss whether this suggestion is correct

For question 1:
Yes the reaction can take place. All properties are conserved
Question 2:
No they are not the same particle. They might have the same charge, but the K^0 has a strangeness of -1, whereas the antikaon has a strangeness of +1

Correct me if I'm wrong but lepton number is not conserved so the reaction cannot happen?
