Particle physics

Perhaps dark matter is made of an entirely different kind of particle than the ones physicists have been searching for. New experiments are springing up to look for these ultra-lightweight phantoms.

Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles — though not yet those of our universe.

Physicists and cosmologists will have a new probe of primordial processes when Europe launches the Laser Interferometer Space Antenna (LISA) next decade.

Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces and pressures inside a subatomic particle for the first time.

By mapping the largest structures in the universe in X-rays, cosmologists have found striking agreement with their standard theoretical model of how the universe evolves.

An idea derived from string theory suggests that dark matter is hiding in a (relatively) large extra dimension. The theory makes testable predictions that physicists are investigating now.

Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.

By measuring inflated helium nuclei, physicists have challenged our best understanding of the force that binds protons and neutrons.

A novel type of neural network is helping physicists with the daunting challenge of data analysis.
