Image showing a neutron and a delta particle emerging from a white flash. The neutron and the delta particle both contain three quarks, represented by colourful spheres. Arrows indicate that the neutron and the delta subsequently undergo a reaction that produces a deuteron (a neutron-proton pair) and a pion.
