Abstract
There are six standard conservation laws of physics: energy, momentum, angular momentum, charge, baryon number and lepton number. It is not generally recognized that there are also a vast number of other conservation laws in physics which are rigorously conserved and quite inde-pendent of these six. A simple proof of these other conservation laws is given as well as examples. The implication of these additional conservation laws is discussed for elementary particles.
Highlights
There are six currently recognized conservation laws in physics
The fifth and sixth conservation laws are purely based on experimental observations of elementary particle interactions and lead to conclusions such as: “The proton does not decay since it is the lowest mass baryon.”
We mentioned above that charge conservation is not just an experimental conservation equation like energy or momentum or baryon number, but can be itself derived from the basic physical theory
Summary
There are six currently recognized conservation laws in physics. The first two (energy and momentum or 4-momentum) are well verified and elegantly included into General Relativity as the stress-energy-momentum tensor Tμν [1]. The fourth conservation law, charge conservation, is experimentally observed, but it shares a unique position among all six conservation laws, because it can be derived directly without any other assumptions once the E & M field tensor is determined. This conservation law is automatically created by the structure of modern physics. The fifth and sixth conservation laws (baryon number and lepton number) are purely based on experimental observations of elementary particle interactions and lead to conclusions such as: “The proton does not decay since it is the lowest mass baryon.”. The fifth and sixth conservation laws (baryon number and lepton number) are purely based on experimental observations of elementary particle interactions and lead to conclusions such as: “The proton does not decay since it is the lowest mass baryon.” Sensitive tests for proton decay have agreed with this conclusion [2]
