IR-Improved Amplitude-Based Resummation in Quantum Field Theory: New Results and New Issues
B. F. L. Ward, S. Jadach, W. Placzek +3
With the advancement of strategies for the precision physics programs for the HL-LHC, FCC-ee, FCC-hh, ILC, CLIC, CEPC, and CPPC, the need for proper control of the attendant theore…
Recent IR-Improved results for LHC/FCC physics
B. F. L. Ward, Aditi Mukhopadhyay, Bahram Shakerin +2
We present recent developments in the theory and application of IR-improved QEDQCD resummation methods, realized by MC event generator methods, for LHC and FCC physics sce…
Comparisons of Predictions from Exact Amplitude-Based Resummation Methods with LHC and Cosmological Data
B. F. L. Ward, S. K. Majhi, A. Mukhopadhyay +1
We present the current status of the comparisons with the respective data of the predictions of our approach of exact amplitude-based resummation in quantum field theory in two are…
The Epsilon Expansion of Feynman Diagrams via Hypergeometric Functions and Differential Reduction
S. A. Yost, V. V. Bytev, M. Yu. Kalmykov +2
Higher-order diagrams required for radiative corrections to mixed electroweak and QCD processes at the LHC and anticipated future colliders will require numerically stable represen…
Differential Reduction Techniques for the Evaluation of Feynman Diagrams
S. A. Yost, V. V. Bytev, M. Yu. Kalmykov +2
Stable reduction methods will be important in the evaluation of high-order perturbative diagrams appearing in QCD and mixed QCD-electroweak radiative corrections at the LHC. Differ…
Feynman Diagrams, Differential Reduction, and Hypergeometric Functions
M. Yu. Kalmykov, V. V. Bytev, Bernd A. Kniehl +2
We will present some (formal) arguments that any Feynman diagram can be understood as a particular case of a Horn-type multivariable hypergeometric function. The advantages and dis…
All order epsilon-expansion of Gauss hypergeometric functions with integer and half/integer values of parameters
M. Yu. Kalmykov, B. F. L. Ward, S. Yost
It is proved that the Laurent expansion of the following Gauss hypergeometric functions, 2F1(I1+a*epsilon, I2+b*ep; I3+c*epsilon;z), 2F1(I1+a*epsilon, I2+b*epsilon;I3+1/2+c*epsilon…
Threshold Corrections in QED otimes QCD at the LHC
B. F. L. Ward, C. Glosser, S. Jadach +1
In some processes at the LHC, theoretical precisions of 1 percent are desired. With an eye toward such precisions, we introduce the theory of the simultaneous YFS resummation of QE…
