Deep inside CERN’s underground labs, the Super Proton Synchrotron has found something incredible. This undercover, four-dimensional force messes with the paths of zooming particles. Hidden in the depths of phase space, this unknown force, called the 4D ghost, throws the delicate dance of particles into chaos.
Scientists at CERN in Switzerland and Goethe University in Germany discovered a mysterious “ghost” that influences how particles move in the Super Proton Synchrotron (SPS). This “ghost” is a 3D shape that changes over time, so it’s best understood in 4D. The idea behind it is similar to why coffee spills when you walk or why your friends fly high on a trampoline bounce.
Physicist Giuliano Franchetti from the GSI in Germany explains the challenge: “Particles often don’t follow the path we plan for them. They deviate, get lost, and this leads to what we call beam degradation.”

The beam phase resonates around the collider and they used the extremes of the resonant path to create a theoretical surface inside of which the resonance takes place. Sadly, it’s not a ghost.
