what is subparticles?

can anyone tell me?

Probably subatomic particles. Protons, neutrons, and electrons. It could also refer to up and down quarks or any of the virtual particles exchanged in the atom such as pions (to hold the nucleas together), photons (to keep the electrons close to the nucleas), gluons (to hold the nucleons together), and weak bosons (in some radioactive decays).

Posting in one of the physics boards will probably give you a more satisfying response.

there are two main groups of subatomic particles: lepitons and quarks. Quarks are the building block of matter. ex. neutrons, protons, neutrinos, etc... while lepitons are just particles that are elementary, ex. photons, electrons.

Photons are not leptons.
 
  • #6
my mistake.
 
  • #7
Neutrinos are leptons.

6 Quarks : Up, Down, Top, Bottom, Charm, Strange
6 Leptons : Electron, Muon, Tau, Neutrino-electron, Neutrino-muon, Neutrino-tau

And yet they are not composed of quarks either, are they? So they're basically some weird exception, kind of a group of its own?



Right. You have two main groups: hadrons and leptons. Hadrons are the particles which can interact via the strong force. examples of hadrons are baryons (like proton, neutron) and mesons . baryons are built out of three quarks with each one colour. Mesons consist of two quarks, a quark and anti-quark. There are six quarks as mentioned above.

Leptons can never feel the strong force. examples are the elektron and the neutrino's (coming from decay-processes) . Leptons feel the elektroweakforce and the gravitational force

Remenber that hadrons can also feel the elektroweak and gravitational force, but it is just that leptons NEVER feel the strong force

These hadrons and leptons build up all matter.

Fotons and gluons and so on are force carriers. The represent the interactions between matter through forces that they represent.

fotons for EM
gluons for strong force
vektorbosons for weak force (decay-processes)

FAQ: Subparticles: Definition & Explanation

What are subparticles?

Subparticles are the smallest known particles that make up atoms and other subatomic particles. They are smaller than protons, neutrons, and electrons and are believed to be the building blocks of matter.

What is the difference between subparticles and subatomic particles?

Subatomic particles are particles that make up atoms, such as protons, neutrons, and electrons. Subparticles, on the other hand, are even smaller particles that make up subatomic particles. They are believed to be the fundamental units of matter.

What are the types of subparticles?

There are several types of subparticles, including quarks, leptons, and bosons. Quarks and leptons are the building blocks of protons, neutrons, and electrons, while bosons are responsible for carrying the fundamental forces of nature.

How are subparticles studied?

Subparticles are studied using particle accelerators, which are powerful machines that can accelerate particles to high speeds and collide them together. Scientists then observe the particles that are produced from these collisions to understand the properties and behaviors of subparticles.

Why are subparticles important?

Subparticles are important because they help us understand the fundamental nature of matter and the universe. By studying subparticles, we can gain insights into the origins and evolution of the universe, as well as develop new technologies and applications in fields such as medicine and energy.
