Role of IR-Improvement in Precision LHC/FCC Physics and in Quantum Gravity
IR-improvement based on amplitude-level resummation allows one to control unintegrable results in quantum field theory with arbitrary precision in principle. We illustrate such resummation in specific examples in precision LHC and FCC physics and in quantum gravity. In particular, we review the history of resummation in quantum field theory from the standpoint of SU2L × U1 × SUc3 Standard Theory, as it is called by Prof. D.J. Gross, with an eye toward both the historical and future perspectives of the subject. We show how the methods developed for the Standard Theory then apply to quantum gravity to yield what appears to be a calculable framework for the Core Theory (Wilczek) as we observe it: the Standard Theory × Quantum Gravity. Some speculations about how susy may still obtain are presented, briefly.
