What is going on in this interaction?

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:

$$\nu_\mu+p\rightarrow e^++e^-+\mu^-+n+K^0$$

The neutron will be invisible and the kaon later decays into

$$K^0\rightarrow\pi^++\pi^-$$

What do you think, is this reasonable?

Any other suggestions as to what may be going on here will be appreciated!

How about now?

Works fine. Don't even have to click and drag.

Unfortunately, I don't know anything about the Standard Model, much less its experiments. I just like looking at pretty pictures. Sorry!

Here is the same picture, but now attached to the forum.

Additional info: the beam (I guess neutrino's?) comes from the left and I guess that it hits a stationary target.

Well the interaction could be part of the one that showed non-conservation of parity. Your kaon decays into two pions, but there are other decays that go into three particles, something that couldn't happen if parity were conserved.
