A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

The muon mismatch was caused by calculation limits, not a new force. Improved methods bring theory and experiment into close ...

For years, one tiny mismatch in particle physics carried outsized hopes. The muon, a heavier and short-lived cousin of the ...

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

Neutrino physics remains a pivotal area in the quest to unravel fundamental aspects of particle behaviour and the evolution of the universe. Neutrinos—elusive, nearly massless particles—are known to ...

World-class particle-accelerator facilities and recent advances in neutron-star observation give physicists a new toolkit for describing nuclear interactions at a wide range of densities. Michigan ...

Scientists are exploring the possibility of a "fifth force" beyond the four known fundamental forces. This hypothetical force ...

In the world of particle physics, you are never alone — quite literally. Every moment there is an invisible rainstorm of subatomic particles falling down on us from space. Unlike the kind of matter we ...
