Is the law of charge conservation absolute?

In connection with possible proton instability some authors admit that the notion 'nuclear charge' is senseless. Objecting to this the possibility for violation of the conservation laws for nuclear and others charges is considered. The profound cause connected with the charge conservation is the preservation of given interaction at the possible charges of one material object. The violation of the charge conservation law means disappearing of given interaction with destruction of given particle or its appearing with the particle reconstruction. The quantum field theory considers the interactions as an exchange of field particles between interacting material objects. One can accept that there are different energy states of the microparticles and a transition between them is taking place when the field particles are absorbed or emitted. This is in accordance with the discreteness of of the micro systems' stable states assembly. But if two energy levels characterize a given micro system they will disappear with its destruction. With disappearing of energy levels the process of transition between them with absorption or emission of the corresponding field particle becomes impossible. This means also disappearing of the corresponding interaction. (author). 6 refs
