In physics, there are two great pillars of thought that don't quite fit together. The Standard Model of particle physics ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted ...

Physicists have identified an algebraic structure underlying the messy mathematics of particle collisions. Some hope it will lead to a more elegant theory of the natural world.

Discover the fascinating world of particle physics — the most fundamental building blocks of the universe and the forces that connect them.

Particles orbiting a black hole could collide at colossal energies, generating collision products that may offer valuable ...

At Fermilab, US physicists are refining their measurements of this subatomic particle—which has major implications for the Standard Model.

Still, the Standard Model is an incomplete theory. Another theory, called supersymmetry, suggests there is an undiscovered partner particle for each one in the Standard Model.

The collision spun off a W-minus boson, an elementary particle that carries the so-called “weak force,” one of four fundamental forces in physics. This phenomenon is called a Glashow resonance.
