Heard of these even more elementary particles

In summary, Preons are even more fundamental particles than quarks and are well accepted in the scientific community. However, the problem with sub-leptonic particles is that their bound states are still not fully understood and do not follow the usual mechanisms for determining mass. A correct theory with proper dynamics is needed to fully understand these particles.

I don't know if anyone has heard of these even more elementary particles, http://en.wikipedia.org/wiki/Preon
There even more fundamental than quarks, i was wondering if they are well excepted into the scientific community or if its a very unlikely that they are real.

They are well excepted but not well accepted.

The problem with sub-leptonic particles is that up to now nobody understands how bound states (ordinary leptons like electrons, neutrinos and quarks) of these sub-leptonic particles can be light.

Usually bound state masses scale with some power of 1/x where x is a typical length scale. This is a rather simple consideration which already works in quantum mechanics: from the size of the Hydrogen atom you can estimate its ionization energy. The order of magnitude comes out right.

But neutrinos are (nearly) massles and (nearly) point like, so somehow the usual mechanism do no longer work.

So it is not enough to put together these objects algebraically, one has to find a theory with correct dynamics.
 

1. What are "even more elementary particles"?

Even more elementary particles refer to the particles that make up the building blocks of matter. These particles are smaller than atoms and are the most fundamental units of matter that cannot be broken down into smaller parts.

2. How are these particles different from regular particles?

These particles differ from regular particles because they are considered to be the most fundamental units of matter. They are smaller and have unique properties that make them distinct from regular particles.

3. Can you give examples of "even more elementary particles"?

Some examples of even more elementary particles include quarks, leptons, and bosons. These particles have been studied and observed in various experiments and are believed to be the fundamental building blocks of matter.

4. How do scientists study these particles?

Scientists study these particles through experiments using high-energy particle accelerators. By colliding particles at high speeds, scientists can observe the behavior and properties of these particles and gain a better understanding of their nature.

5. Why are these particles important to study?

These particles are important to study because they help us understand the fundamental nature of matter and the universe. By studying these particles, scientists can gain insights into the origins of the universe and potentially unlock new technologies and advancements in various fields.
