The term "Particle Physics" is a little bit misleading. "High Energy Physics" is more accurate to describe this discipline. In our current understanding of Quantum Mechanics in the framework of "Quantum Field Theory" (which is the mathematical tool to study Particle Physics) every thing whether it's matter or interaction is basically a smooth field occupying a region of the Space-time. This field is waves and not particles. Particles only appear when the fields are excited in a point of the Space-time. They are "excitation" of the fields.
In the modern perspective and revision of basic Quantum Mechanics, the Wave-Particle Duality postulate is not 100% symmetry or duality between waves and particles, the waves are considered to be more fundamental than particles.
Furthermore, in Superstring theory, the particles are suggested to be waves of tiny one dimensional strings vibrating in 10 dimensional space and each mode of vibration gives birth to a particular particle of matter or interaction. As a consequence, the three points vertex in Feynman Diagrams ( the sticks representing the interactions) transforms from a point to a smooth tube of strings.
