Each diagram captures one possible sequence of subatomic events and gives an equation for a number, called an “amplitude,” that represents the odds of that sequence taking place.

The new subatomic particle is called the beauty-lambda baryon.It belongs to a group of particles known as baryons, which include protons and neutrons. These particles are made of three quarks.

The Standard Model organizes the subatomic world into two broad categories of particles, known as fermions and bosons, according to the University of Tennessee, Knoxville.

Protons are tiny particles just a femtometer across, but without them, atoms wouldn't exist. Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The ...

Neutrinos are ghostly subatomic particles that can travel in a straight line for billions of light-years, passing unhindered through galaxies, stars and anything else in their path.

Particles, or bits of matter, range in size and can be larger or smaller than atoms. Electrons, protons and neutrons, for instance, are the subatomic particles that make up an atom.

Neutrinos are ghostly subatomic particles that can travel in a straight line for billions of light-years, passing unhindered through galaxies, stars and anything else in their path.

Most exotic hadrons, which are subatomic particles, are made up of two or three elemental particles known as quarks. The strong force is one of four forces known in the universe, ...
