Light-by-light scattering is a rare phenomenon in which two photons—particles of light—interact, producing another pair of photons. Direct observation of this process at high energy had proven elusive for decades, until ...

Visible matter—everything from pollen to stars and galaxies—accounts for roughly 15% of the total mass of the universe. The remaining 85% is made of something entirely different from things we can touch and see: dark ...

The Higgs boson was discovered by the ATLAS and CMS Collaborations at CERN's Large Hadron Collider (LHC) in 2012 through its decays into pairs of photons, W bosons and Z bosons. Since then, physicists at these experiments ...

When a particle is transformed into its antiparticle and its spatial coordinates inverted, the laws of physics are required to stay the same—or so we thought. This symmetry—known as CP symmetry (charge conjugation and ...

Two years ago, the Higgs boson was observed decaying to a pair of beauty quarks (H→bb), moving its study from the "discovery era" to the "measurement era." By measuring the properties of the Higgs boson and comparing them ...

What if you could test a new theory against data from the Large Hadron Collider (LHC)? Better yet, what if the expert knowledge needed to do this was captured in a convenient format? This tall order is now on its way from ...

The universe is governed by four fundamental forces: gravity, electromagnetism and the strong and weak nuclear forces. These forces drive the motion and behavior of everything we see around us. At least, that's what we think. ...
