Yesterdays Science (SM Quantum Loops) Becoming Tomorrows Engineering/Applied Mathematics (How Resumming Loops from Yesterday Allows Observation of New Loops from Tomorrow)†

In the late 1960s, a seminal work by Prof. Steven Weinberg on a unified theory of weak and electromagnetic interactions, the SU2L×U1 electroweak theory, was published in Physical Review Letters. Profs. Sheldon L. Glashow and Abdus Salam independently published the same theory in the 1960s in the journal Nuclear Physics and in the 8th Nobel Symposium, Stockholm, respectively. This work, together with the seminal publications, also in Physical Review Letters, by Profs. David J. Gross, Frank Wilczek and H. David Politzer on an asymptotically free gauge theory of the strong interactions, QCD, in the early 1970s, has created the current theoretical paradigm which has ~50 years of successful predictions for what we call the Standard Model of Elementary Particle Physics. We may now actually call it the Standard Theory of Elementary Particle Physics as Prof. Gross has recently suggested. It is a framework in which quantum loop corrections to the electromagnetic, weak and strong interactions can be done in principle to arbitrary orders in their respective coupling constants. We discuss how in working to higher orders in this framework we have been able to help to prove the correctness of the Standard Theory of Elementary Particle Physics and how, in extending the respective higher order methods toward the future colliders under study for the so-called Energy Frontier in elementary particle physics, we are in position to aid in the potential discovery of heretofore unseen degrees freedom. These new degrees of freedom would then generate the new quantum loops of tomorrow. Indeed, this paradigm would appear to have the potential for unlimited replication going forward.
