Hi! I have a beautiful picture of some interaction that I want to explain with the standard model. I think it's probably a famous one, but I have no idea where & when I found it. If anybody recognises this data, then I'd be very happy to hear what it is... For now, I am guessing something like: [tex]\nu_\mu+p\rightarrow e^++e^-+\mu^-+n+K^0[/tex] The neutron will be invisible and the kaon later decays into [tex]K^0\rightarrow\pi^++\pi^-[/tex] What do you think, is this reasonable? Any other suggestions as to what may be going on here will be appreciated!
