After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest ...

Collaboration that made precise measurement of the g-2 value honored with $3 million from the Breakthrough Prize in ...

In 2021, the first result from the Muon g-2 experiment at Fermilab confirmed a two-decade-old measurement from Brookhaven, ...

Its value describes the strength of the gravitational force acting on two masses separated by a given distance—or if you want to be relativistic about it, the amount a given mass curves space-time.

The new calculation, made at the Large Hadron Collider (LHC) near Geneva, could help solve a niggling mystery about this ...

For a few years, one of particle physics’ most unsettling numbers seemed to be pointing somewhere strange. The trouble ...

And then we drive this very cylindrical-looking, saucer-shaped device out in the middle of the night, in the rain Chris Polly ...

The ALPHA collaboration at CERN reports an important milestone on the way to measuring the properties of antimatter atoms. This follows news reported in June last year that the collaboration had ...

BATAVIA, Illinois — The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the ...
