What is a particle ?

At higher energies, the so-called "waves" behave more and more like wave packets, which are closer to particles than waves. That's why the Standard Model is about particles. You get tables listing the particles and their properties - mass, spin, charge, parity, etc. One of the striking differences between QM and QFT textbooks is the absence of the wave model in the latter.
