Back in the 1930s, physicists were doing experiments involving what they called "beta decay." They observed that an element would suddenly spit out a fast-moving electron, and once it was done, it ...

The weak nuclear force transforms one type of particle into another. This video explains why it’s called a "force"—showing ...

The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear ...

A new result from the Q-weak experiment at the Department of Energy’s Thomas Jefferson National Accelerator Facility provides a precision test of the weak force, one of four fundamental forces in ...

As the carriers of the weak force, the W and Z bosons are central to the Standard Model of particle physics. Though discovered four decades ago, the W and Z bosons continue to provide physicists with ...

Add Yahoo as a preferred source to see more of our stories on Google. The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four ...

David Kaplan has developed a lattice model for particles that are left- or right-handed, offering a firmer foundation for the theory of weak interactions. David Kaplan is on a quest to straighten out ...

Scientists have gained insights into the weak nuclear force from new, more sensitive studies of the beta decays of the 'mirror' nuclei lithium-8 and boron-8. The weak nuclear force drives the process ...

Left: “Mirror” nuclei lithium-8 and boron-8 undergo beta decay, then split into two alpha particles. Right: Radioactive ions from the ATLAS accelerator at Argonne National Laboratory are suspended in ...
