A major obstacle in calculating the muon’s behavior is the strong force, the most powerful of the four fundamental forces, along with gravity, electromagnetism, and the weak force. It binds quarks ...

A major physics experiment has uncovered evidence for a strange new form of matter, where a fleeting particle gets trapped ...

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

“We weren’t even looking for a semi-Dirac fermion,” said Yinming Shao, a physics professor and lead author on the study. “We were seeing signatures we didn’t understand — and it turns out we had made ...

A cosmic particle detector flying high over Antarctica picked up a series of strange radio signals that appeared to be coming from below the ice - something current particle physics says shouldn’t be ...
