Thanks for the quick reply. After thinking about it for a few minutes, I figured it had to be gluons scattering from somewhere.

This Feynman diagram accompanied the announcement on the public LHCb site. How would you describe the origins of the up and down quark anti-quark pairs that that contribute to the decay of the ##\Xi_{cc}^{++}##?

Just testing my current knowledge- would the particle ##X## be a ##\Sigma^+## ? And would this be the corresponding Feynman diagram? Also, rather than a gluon, could the mediation particle be a photon or ##Z^0##?

Thanks, that explains it perfectly.

A meson can be produced by a high energy photon scattering off a nucleon in an interaction such as $$\gamma + p \rightarrow p + \pi^0$$ As long as the photon is sufficiently energetic, mesons heavier than the pion can be produced, as well as multiple mesons such as ##\pi^{+} + \pi^{-}##...
