Particles

In summary, particles are tiny units of matter that make up everything in the universe, including atoms and subatomic particles. There are currently 17 known particles in the Standard Model of particle physics, which have characteristics such as mass, spin, charge, and interactions with other particles. These characteristics determine how particles behave and interact with each other. Fermions, which make up matter, have half-integer spin and follow the Pauli exclusion principle, while bosons, which carry forces, have integer spin. Lastly, particles cannot be created or destroyed, but can be converted into different types through interactions.

Where on the internet can I find a listing of the known particles and all there charateristics like mass and charge?

Also a listing of all the quarks and characteristics?

Thanks

at the particle data group.
It is the group in charge of it during tha last quarter of century. www.pdg.somewhere...[/URL]

Thanks.
That's a big help

1. What are particles?

Particles are tiny units of matter that make up everything in the universe, including atoms and subatomic particles.

2. How many known particles are there?

There are currently 17 known particles in the Standard Model of particle physics, which is the most widely accepted theory of particle interactions.

3. What are the characteristics of particles?

Particles have several characteristics, including mass, spin, charge, and interactions with other particles. These characteristics determine how particles behave and interact with each other.

4. What is the difference between fermions and bosons?

Fermions are particles that make up matter, such as protons, neutrons, and electrons. They have half-integer spin and follow the Pauli exclusion principle, which states that no two fermions can occupy the same quantum state. Bosons, on the other hand, are particles that carry forces and have integer spin. Examples include photons and gluons.

5. Can particles be created or destroyed?

In accordance with the law of conservation of mass and energy, particles cannot be created or destroyed. However, particles can be converted into different types of particles through interactions, such as nuclear reactions or particle collisions.
