Hi everyone...

I have answered already a lot of questions here on the topic of the different elementary particles in the Standard Model. For this reason I will give the interested reader this site that describes this subject very clearly...

http://pdg.web.cern.ch/pdg/particleadventure/frameless/startstandard.html

If you have more questions, please don't hesitate to post them here...

marlon

Hi
marlon
I have a very fundamental question please help me
Are electrons really close to structure less point charged particles?
Since I am not getting convinced from theory, is it the experiments that makes us believe so,then why is its size being revised year after year.
Are we missing something very fundamental?
Regards
Shankar

We have so far no experimental signs of size or structure of the electron; experimentally we can only deduce the UPPER LIMIT - and that limit changes as we reach higher and higher energies in our laboratories.

The upper limit of the electron radius is 10^-21 meters I think, thus we have not said that "the size of the electron IS 10^-21 meters", we have only said "IF the electron has size, then it is smaller than 10^-21meters".
