Overview of IR-Improvement in Precision LHC/FCC Physics

Abstract

We present an overview of the use of IR-improvement of unintegrable singularities in the infrared regime via amplitude-based resummation in $\mathrm{QED}\times \mathrm{QCD}$ $\subset$ $\mathrm{SU}(2{)}_L\times {\mathrm{U}}_1\times \mathrm{SU}(3{)}^c$. We work in the context of precision LHC/FCC physics. While illustrating such IR-improvement in specific examples, we discuss new results and new issues.
