QCD for electroweak precision measurements: Foundations
George Sterman
The couplings of the strong to electroweak sectors of the Standard Model enable the exploration of each using our growing knowledge of the other. In this review, we will follow the…
Ward identity preserving local ultraviolet counterterms for photoproduction at two loops in QCD
Charalampos Anastasiou, Julia Karlen, Roshni Sahoo +2
We review the construction of locally finite two-loop amplitude integrands for photoproduction via quark annihilation, presented in arXiv:2509.07805. Building on established techni…
Local finiteness for real-virtual corrections to electroweak production in partonic collisions
Charalampos Anastasiou, Julia Karlen, Yao Ma +1
We present a local subtraction scheme that enables the combined integration of loop momenta and the final-state parton phase space in real-virtual NNLO QCD corrections to cross sec…
General finite two-loop amplitude integrand for photoproduction in quark annihilation
Charalampos Anastasiou, Julia Karlen, Roshni Sahoo +2
The construction of integrands free of infrared and ultraviolet singularities may enable the application of numerical methods to evaluate loop amplitudes that are inaccessible with…
Coordinate light-cone-ordered perturbation theory
Ozan ErdoÄan, George Sterman
We review the development of light-cone-ordered perturbation theory in coordinate space (C-LCOPT). Compared to light-cone-ordered perturbation theory in momentum space (LCOPT), the…
Locally finite two-loop amplitudes for electroweak production through gluon fusion
Charalampos Anastasiou, Julia Karlen, George Sterman +1
The computation of two-loop amplitudes for the production of multiple Higgs and electroweak gauge bosons via gluon fusion with exact dependence on quark masses relies primarily on…
