Ultrahigh energy photons striking matter can transform into rho mesons through an interaction that involves many nuclei simultaneously, a phenomenon that may affect the detection signatures of high-energy particles from space.

Colliding protons can remain intact but still generate new particles, according to results from Fermilab. A similarly clean process could produce the elusive Higgs particle at CERN’s Large Hadron Collider.
