Bosons are wave packets caused by vibrations and rotations of the composing
particles of an atom.
Below a schematic structure of an H atom, showing how photons, gluons, neutrinos
and W/Z bosons are related to the corresponding situation within the atom.
Wave packets have a mass (volume) if they push z particles apart, and cause a reduced local time rhythm.
Wave packets have a charge if their average time-rhythm is not equal to the local time-rhythm.
