The study of electric dipole moments (EDMs) offers a unique window into the violation of time-reversal symmetry, an effect that, when coupled with charge-parity (CP) violation, presents fundamental ...

Do electrons have a fourth property in addition to mass, charge and spin, as popular physics theories such as supersymmetry predict? Researchers from Germany, the Czech Republic and the United States ...

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 ...

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 ...

Monitoring precession: The researchers measured the electron electric dipole moment in hafnium fluoride ions confined within an ion trap. (Courtesy: Casey Cass/University of Colorado) One way to look ...
