I will collate my comments here:
The Standard Model of particle physics encapsulates almost all the experimental evidence to date about particles and their interactions. It consists of two branches, the particles and their observed symmetries under interactions and also the quantum mechanical mathematical tools that give the interaction probabilities for desired reactions between them.
The Standard Model of elementary particles, with the three generations of matter, gauge bosons in the fourth column and the Higgs boson in the fifth.
We see from the list of elementary particles that masses, spins, charges are intrinsic attributes. Among the charges one should include the three QCD colors and also lepton number and baryon number.
The symmetries that have been established experimentally led to the specific mathematical model.
Mathematical models need variables, these are the four space time dimensions (x,y,z,t) and the energy momentum vector (p_x,p_y,p_z,E) which will describe the kinematics of interacting particles. Based on these variables Quantum mechanical equations represent the dynamics of interacting elementary particles .
