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, ...

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 ...

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 ...

A new result from the Q-weak experiment provides a precision test of the weak force, one of four fundamental forces in nature. The proton's weak charge was found to be QWp=0.0719±0.0045, in excellent ...

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 ...
