Join six leading experts to find out everything we know about the subatomic universe. Take a deep dive into the building ...

S cientists can determine the mass of subatomic particles that are built from quarks by looking at the particles' energy and momentum in four-dimensional spacetime. One of the quantities that ...

The majority of our evidence for dark matter’s existence comes from observing visible (or baryonic) matter that does not ...

Dirac fermions have mass and aren’t their own anti-particles ... in table-top experiments — whereas to discover subatomic particles we often need huge colliders,” Agarwala said.

Our home planet is bombarded with particles from outer space all the time. And while we are mostly familiar with the rocky ...

The expected frequency of scattering of particles of different mass, if they are subject only to Coulomb forces in collisions with nuclei of the atoms composing the emulsions, can be calculated.

Neutrinos are a type of subatomic particle ... detail because neutrinos may get their mass through a different mechanism from other matter particles. Unravelling it could answer many open ...

A compact method of detecting neutrinos provides new tests of physics theories and could lead to new reactor-monitoring methods.

Scientists discover low-mass microquasars can accelerate cosmic rays, reshaping theories on high-energy particle origins.

Muon spin rotation (µSR) spectroscopy is a powerful technique that helps to study the behavior of materials at the atomic ...
