Excitement grows as Large Hadron Collider hints at new particle
Mar 19, 2016

When hundreds of physicists gathered this week in La Thuile, an old mining town in the heart of the Italian alps, one short and simple question hung in the cool, crisp air: is it real?
The source of their fascination, and no little excitement, was light. Not the sunlight that made the snow glint on the mountains in the Aosta valley, but light inside the Large Hadron Collider (LHC) across the border near Geneva. The machine had detected more photons than expected as it smashed particles beneath the quiet Swiss countryside. The brief flashes of light might be the first glimpse of the next big discovery.
Or it may be nothing. The LHC hunts for signs of new physics by slamming particles together and capturing the debris in giant detectors. It is a world where quantum weirdness rules, and random blips in the data are a daily nuisance. But what if this latest bump in the data has solid foundations? Enter a new era of physics, and a world of hitherto unknown particles and forces.
Speculation is rife. Some physicists suspect that the blip may be a heavier cousin of the Higgs boson, the mass-giving particle the LHC discovered in 2012. Alternatively, it could mean the Higgs itself is made up of a bunch of smaller particles. Others wonder if the bump might be a graviton, a particle that transmits gravity. That would be truly remarkable: so far, gravity has proved impossible to reconcile with theories of other particles and forces.

Mean while the AWAKE experiment, under construction at CERN, is preparing to test proton-driven plasma wakefield acceleration. This method could accelerate particles with hundreds of times more power than current methods.
