Even if you’re one of the most precise physicists on the planet — as University of Delaware Professor Marianna Safronova is — you still will need collaborators whose skills complement your own and ...

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, ...

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 ...

The weak charge of the proton has been measure to high-precision for the first time. The work was done at the Thomas Jefferson National Accelerator Facility (Jefferson Lab) in Virginia and the result ...

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 ...

When scientists fire beams of electrons at atomic nuclei, the resulting scattering patterns usually behave exactly as theory predicts. It’s one of the great strengths of modern nuclear physics. This ...

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 ...
