New Developments in KKMChh: Quark-Level Exponentiated Radiative Corrections and Semi-analytical Results
arXiv:2111.14567 · doi:10.21468/SciPostPhysProc.7.016
Abstract
We describe a new semi-analytical program, KKhhFoam, which provides a simplified framework for testing the amplitude-level exponentiation scheme (CEEX) of the full KKMChh program in the semi-soft limit. The structure of the KKhhFoam integrand is also helpful for elucidating the structure of CEEX. We also discuss the representation of ISR in KKMChh and compare the ISR added by KKMChh to the effect of switching to a QED-corrected PDF, at the individual quark level, and suggest a new approach to running KKMChh with QED-corrected PDFs.
