what is subparticles???

[alanveron]

can anyone tell me?

[turin]

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.

[turin]

Photons are not leptons.

[Nenad]

my mistake.

[Gonzolo]

Neutrinos are leptons.

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

[marlon]

And yet they are not composed of quarks either, are they? So they're basically some wierd 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

[marlon]

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)
