Colliding light to make dark matter and measure tau g–2

Dark matter is mysterious because it doesn’t interact with light. How remarkable it would be if we made it in the lab by colliding light. Using the LHC as the highest energy broadband photon collider ever built opens dark matter searches using the missing momentum 4-vector via proton tagging. I then propose using heavy ion beams to measure tau g–2, which is barely constrained but potentially 280 times more sensitive to new physics than muon g–2.
