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 ...

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 ...

No new particles: artist’s impression of how virtual particles could give the electron an electric dipole moment. (Courtesy: Nicolle Fuller/NSF) It is well known that the electron has a magnetic ...

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 ...

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 ...
