The LHCb experiment has taken a leap in precision physics at the Large Hadron Collider (LHC). In a new paper submitted to Physical Review Letters and currently available on the arXiv preprint server, ...

Students distinguish between accuracy and precision of measurements. Accuracy, Precision, and Significant Digits: Students distinguish between accuracy and precision of measurements and make ...

Precision measurements in atomic and ion physics have become a cornerstone for testing the limits of our understanding of quantum electrodynamics (QED) and the Standard Model. By harnessing ...

Tick tock: Artist's impression of a quantum clock. (Courtesy: Alexander Rommel/TU Wien) The second law of thermodynamics demands that if we want to make a clock more precise – thereby reducing the ...

A team of theoretical high-energy physicists has published a new high-precision calculation that could significantly advance the indirect search for physics beyond the Standard Model. The calculation ...

An ultra-precise clock that ticks to the beat of hydrogen molecules could probe fundamental constants and maybe spot signs of new physics. Atomic clocks are the world’s most accurate timekeepers. They ...

The final result from the Muon g-2 Experiment has exceeded all expectations, achieving a precision likely to remain unmatched for generations. Yet, recent tensions in theoretical predictions have put ...

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the particle many hoped would explain it. Baryons, composite particles made up of ...
