In a study that closes a long-standing knowledge gap in fundamental science, researchers Boerge Hemmerling and Stephen Kane at the University of California, Riverside, have successfully measured the ...

Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...

Physicists are closer to finding out if the electron is a point charge or whether it has an internal distribution of charge known as an electric dipole moment. For the first time, Ed Hinds and ...

Studies that test some physical property to an extreme precision are gaining in popularity these days because many physicists are intently looking for small chinks – too small for them to have noticed ...

Electric dipole moments (EDMs) are a crucial area of research in particle physics, particularly in the context of understanding the fundamental symmetries of nature. The study of EDMs is closely ...

The most precise measurement yet of the electron’s shape casts doubt on ideas such as supersymmetry that predict a zoo of undetected particles in the universe Scientists are unanimous that their ...
