The standard model of quantum physics Clifford algebra We extend to gravitation our previous study of a quantum wave for all particles and antiparticles of each generation (electron + neutrino + u and d quarks for instance). This wave equation is form invariant under Cl3* then relativistic invariant. It is gauge invariant under the gauge group of the standard model with a mass term: this was impossible before and the consequence was an impossibility to link gauge interactions and gravitation
