Question

Which types of particles are involved in strong interactions? Explain it with two examples and also draw Feynmen diagram.

Answer 1

Gluons are involved in strong interactions. They tie hadrons together.

As we see in the following diagram, the jet of hadrons is a result of the interaction between a quark and antiquark.

In the following diagram we see how the quark emits a gluon:
