Scientists are using trapped ions in cutting-edge experiments to hunt for signs of an undiscovered particle that might help ...

The Standard Model predicts that quark-containing composite particles ... A diagram of neutrinoless double beta decay, which involves the simultaneous decay of two down ...

Together, quantum chromodynamics and the electroweak model make up the Standard Model of particle physics, with a Lie group formed by combining SU(3), SU(2) and U(1), as well as matter in several ...

Normally a statistical significance of five standard definitions – equivalent to around a 1 in 3.5 million chance of being a coincidence – is required to declare something a “discovery.” ...

Holger Müller is in the Department of Physics, University of California, Berkeley, Berkeley, California 94720, USA. However, the recoil energy is tiny and therefore hard to measure. Laser-based ...
