What is a application of linear sigma model?

In summary, the linear sigma model is used to describe the interaction of pion particles at low energy. Pion particles are a type of meson particle that play a role in the strong force, which is carried by gluons resulting from SU(3). The Yukawa theory, which is an older theory, is not currently used. The residual interaction between protons and neutrons to form an atomic nucleus is similar to the corresponding force between Van der Waals and electromagnetic, and is theorized to be caused by "virtual" pion particles.

Please teach me this:
Which interaction is the result of linear sigma model.Please teach me what purpose the linear sigma model implies?
Thank you very much in advanced.

I have just heard that this model describe the pions interaction at low energy.But what is pion particles?

It seem to me the strong force is carried by gluon resulted by SU(3),why we need meson particles to describe the subatomic phenomena?Is Yukawa theory a old theory(not using at the moment)?

At the moment,I have just known that the interaction between protons and neutrons to form atomic nucleus is residual interaction caused strong interaction carried by gluons similar with the corresponding between Van der Waals force and electromagnetic.This interaction is theorized by ''virtual'' pion particles.Is that correct?Thank you very much for any your teaching.

Sorry,...residual interaction caused by strong interaction...
