Subatomic particles are best described with fuzzy math. We don't know exactly where an electron is — but we know the odds that it's at a certain point in a general area that is ringed by a boundary.

W bosons are subatomic particles responsible for a fundamental force at the centre of atoms. They exist for only a fraction of a second before they decay into other particles. W bosons govern what ...

particle: A subatomic object with a definite mass and charge. Currently known elementary matter particles are grouped into categories of quarks and leptons and their antimatter counterparts.

We present a novel detector for measuring the charge and mass of micron-sized particles. Detection of charge is based on charge induction on electrodes connected to a custom differential amplifier.

CERN physicists observed matter-antimatter imbalance in a baryon. Antiparticles possess the same mass as matter but opposite charge. The Big Bang should have created equal matter and antimatter.

Of all the subatomic particles that have any mass at all, the neutrino is the lightest by far. In comparison, the electron, itself a quantum featherweight, has a mass that is at least 500,000 ...

Both particles were predicted to exist by the quark model in physics, but had never been seen before, although a related particle, Xi_b*0, was spotted by the CMS experiment at CERN in 2012.

The Standard Model Orders or magnitude allow physicists to compare very large and very small distances. The range of subatomic particles and fundamental forces are the cutting edge of modern physics.

The sun supports itself by transforming hydrogen into helium. Neutrinos are one by-product of this alchemy. These particles have so little mass, they barely exist at all; roughly 10 billion ...
