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 ...

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

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 ...

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 ...

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 ...

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 ...

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 ...

When you hear the phrase “straight as an arrow,” you might imagine a perfectly linear trajectory. But in reality, an arrow’s flight is anything but straightforward. Enter the archer’s paradox – a ...
