Scientists are using “trapped ions” in highly precise experiments to search for a new, fifth force of nature that could help explain elusive dark matter. The invisible dark matter is one of the ...

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 ...

Physicists are closing in on a strange, hidden influence that does not fit neatly into the four familiar forces of nature, and the search is reshaping how detectors are built and where they are ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most ...

A chameleon-like force that shifts its nature based on its environment could explain a major physics quandary: how the mysterious substance called dark energy is compelling the cosmos to expand faster ...

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 ...
