Neutrinos are extremely lightweight and electrically neutral particles that rarely interact with ordinary matter. Due to ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Garching, in collaboration with Prof. Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

Cracking a 15 year physics mystery, researchers measured the precise size of a proton. In A Nutshell A team in Germany used an unprecedentedly precise laser measurement of hydrogen to pin down the ...

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

The magnetic moment of the muon is an important precision parameter for putting the Standard Model of particle physics to the test. After years of work, the research group led by Professor Hartmut ...

Dr. Randolf Pohl from the Institute for Physics at Johannes Gutenberg University Mainz (JGU), have successfully conducted experiments on hydrogen atoms which allow testing of the Standard Model of ...

The Standard Model of particle physics, which describes the currently known elementary particles, has been in place since the 1970s. Nature can still surprise us, but it typically requires larger or ...
