The Standard Model of particle physics describes all of the known elementary particles and three of the four known forces that define how they interact with each other: the electromagnetic force ...

Physicists have caught neutrinos from a nuclear reactor using a device weighing just a few kilograms, orders of magnitude ...

Neutrinos, ghostly particles barely interacting with matter, may secretly be reshaping the fates of massive stars. New ...

Neutrinos were elementary particles that interacted with matter only on a very weak scale, making their experiments massive ...

Researchers at CERN have observed for the first time that matter and antimatter behave differently in decaying, heavy ...

Overcoming discrimination in a mostly male preserve, she did groundbreaking work that showed experimentalist physicists where ...

That is, particles have energy, and their gravitational interaction should occur through the exchange of some hypothetical carrier particles — quanta of the gravitational field. The peculiarity of ...

Experiments using the Tevatron accelerator at the Fermi National Accelerator Laboratory in the United States have shown that the W bosons of weak bosons , which are elementary particles that ...

In the Standard Model, elementary particles are manifestations of three “symmetry groups”—essentially, ways of interchanging subsets of the particles that leave the equations unchanged.
