ajb Posted February 16, 2015 Share Posted February 16, 2015 Quarks and gluons carry colour charge and so interact directly via the strong force, ie. quantum chromodynamics. By strong force one could also mean the residual strong force which is responsible for the nucleons in a nucleus bonding together. This is less well understood from a fundamental point of view. Note that although the nucleons themselves are colourless on net this residual strong force is an effect of the 'fundamental' strong force. 1 Link to comment Share on other sites More sharing options...
swansont Posted February 16, 2015 Share Posted February 16, 2015 What particles can have strong interaction? What particles can't have strong interaction? Particles built from quarks use the strong interaction, i.e. Hadrons (baryons and mesons). Those that are not, do not. http://en.wikipedia.org/wiki/Hadron 1 Link to comment Share on other sites More sharing options...

Then, when the distance is increasing, fields of the quarks are shifting to each other, it increases force of interaction.

Mordred Posted February 18, 2015 Share Posted February 18, 2015 As the distance between two quarks expand, more gluons form and the strength of the strong nuclear field increases. This is called asymptotic freedom. Link to comment Share on other sites More sharing options...
Strange Posted February 18, 2015 Share Posted February 18, 2015 This is called asymptotic freedom. I can't help thinking it should be called "asymptotic lack-of-freedom." Link to comment Share on other sites More sharing options...

Lol I like the term/idea of quark confinement So do I, textbooks vary between the two terms. Coincidentally I found "Quarks and Leptons" a good intro textbook. Though Griffiths "Introductory to particle physics" in my opinion is still the better choice for intro books. Link to comment Share on other sites More sharing options...
