Large Hadron Collider

Physicists are confronting their “nightmare scenario.” What does the absence of new particles suggest about how nature works?

Three physicists have proposed a new solution to one of the deepest mysteries in particle physics: why the Higgs boson has such a tiny mass.

A statistical anomaly in the signal from rare particle decays at the Large Hadron Collider offers hope that new discoveries might be around the corner.

As the elegant theory of supersymmetry continues to fail experimental tests, physicists debate whether to change course and what the future holds for particle physics.
