New technique uses near-miss particle physics to peer into quantum world − two physicists explain how they are measuring wobbling tau particles

Physicists uncovered a new experiment hidden in old data from the Large Hadron Collider. Using this innovative approach, the team has unlocked an entirely new way to study quantum physics.

Researchers dig deep underground in hopes of finally observing dark matter

To detect dark matter, you need to build an ultra-sensitive detector and put it somewhere ultra-quiet. For one physics collaboration, that place is almost a mile under Lead, S.D.
A new particle accelerator at Michigan State University is set to discover thousands of never-before-seen isotopes. Facility for Rare Isotope Beams

Powerful linear accelerator begins smashing atoms – 2 scientists on the team explain how it could reveal rare forms of matter

A new particle accelerator has just begun operation. It is the most powerful accelerator of its kind on Earth and will allow physicists to study some of the rarest matter in the universe.

What is quantum entanglement? A physicist explains the science of Einstein’s ‘spooky action at a distance’

A multitude of experiments have shown the mysterious phenomena of quantum mechanics to be how the universe functions. The scientists behind these experiments won the 2022 Nobel Prize in physics.

A decade of science and trillions of collisions show the W boson is more massive than expected – a physicist on the team explains what it means for the Standard Model

A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Experiments at the Large Hadron Collider in Europe, like the ATLAS calorimeter seen here, are providing more accurate measurements of fundamental particles. Maximilien Brice

2021: a year physicists asked, ‘What lies beyond the Standard Model?’

Physicists know a lot about the most fundamental properties of the universe, but they certainly don’t know everything. 2021 was a big year for physics – what was learned and what’s coming next?
