Scientists on an experiment at the Large Hadron Collider see massive W particles emerging from collisions with electromagnetic fields.
The Large Hadron Collider plays with Albert Einstein’s famous equation, E = mc², to transform matter into energy and then back into different forms of matter.
But on rare occasions, it can skip the first step and collide pure energy—in the form of electromagnetic waves.
Last year, the ATLAS experiment at the LHC observed two photons, particles of light, ricocheting off one another and producing two new photons.
This research doesn’t just illustrate the central concept governing processes inside the LHC: that energy and matter are two sides of the same coin.
It also confirms that at high enough energies, forces that seem separate in our everyday lives—electromagnetism and the weak force—are united.
Instead, you’ll see the two beams combine to form an even brighter beam of light. »
