the theory which describes elementary particles and their interactions is
called quantum field theory. There, all particles are described on the
same footing, namely as (quantized) fields.
Usually one distinguishes between matter fields and interaction fields.
Particles like electrons, quarks or protons and neutrons are matter
fields, since they are the basic building blocks of matter. These
particles interact with each other via exchange of interaction particles,
such as photons or gluons. For a reference see this introduction, for example.
