The {\bf Daon theory} is a new general theory of physics, it is a completely new way to approach physics and includes, in principle, all phenomena of nature. The theory is presented in a series of closely related papers treating Electromagnetism, Atomic physics, Particle physics, Relativity, Gravitation and Cosmology. They should be red in this order for a complete understanding. The numerical value of the main natural constants and parameters are calculated, while the explanation for the various natural phenomena are simple and logical. All the results from this theory agree, as far as we know, with experimental data. The theory is constructed on the basis of one unique fundamental object {\bf the Daon}, which is the ultimate constituent of all matter. It is a very small rotating sphere. The daon's size, velocity of rotation and associated "mass" are all fixed by experimental evidence or geometrical necessity\cite{1}. In this document we present the photon and the neutrino, as seen from the perspective of the Daon Theory. We thereafter examine the muon, the $\pi^0$, the $\pi^+$, the proton and the neutron, with the help of a code of simulation. The particles are presented in a very detailed manner since any value of interest can be obtained from any of the constituents of the examined particles.
