In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model...

Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies...

This is a list of known and hypothesized particles. Elementary particles are particles with no measurable internal structure; that is, it is unknown whether...

theory (QFT). Force particles, called gauge bosons—force carriers or messenger particles of underlying fields—interact with matter particles, called fermions...

By contrast, elementary particles (also called fundamental particles) refer to particles that are not made of other particles. According to our current...

problem in physics. Particle physicists study matter made from fundamental particles whose interactions are mediated by exchange particles – gauge bosons –...

messenger particle, intermediate particle, or exchange particle) is a type of particle that gives rise to forces between other particles. These particles serve...

set of fewer fundamental particles than those of the Standard Model, together with the rules governing how those fundamental particles combine and interact...

constituent particles (ions, atoms, or molecules) are closely packed together. The forces between particles are so strong that the particles cannot move...

particle, which is not composed of other particles (for example, quarks; or electrons, muons, and tau particles, which are called leptons). Particle physics...

actual particles. At one time neutrinos were thought to perhaps be Weyl fermions, but when they were discovered to have mass, that left no fundamental particles...

nuclear physics and particle physics, the strong interaction, also called the strong force or strong nuclear force, is a fundamental interaction that confines...

because many elementary particles do not occur naturally but are created only during high-energy collisions of other particles. Currently, the interactions...

interaction. Those particles are called force carriers or messenger particles. Despite being perhaps the most familiar fundamental interaction, gravity...

Like all elementary particles, electrons exhibit properties of both particles and waves: They can collide with other particles and can be diffracted...

ignored so it can be treated as a pointlike object, i.e. a point particle. Point particles with electric charge are referred to as point charges. Two point...

fermions. However, instead of a single fundamental particle, they are the collective movement of several individual particles (themselves composite) which are...

string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings....

nuclear force is a short distance force that takes place between fundamental particles within a nucleus. It is charge independent and acts equally between...

subatomic particles, and in everyday as well as scientific usage, matter generally includes atoms and anything made up of them, and any particles (or combination...
