Master Integrals for Four-Loop Massless Form Factors
Roman N. Lee, Andreas von Manteuffel, Robert M. Schabinger +3
We present analytical results for all master integrals for massless three-point functions, with one off-shell leg, at four loops. Our solutions were obtained using differential equ…

Fermionic corrections to quark and gluon form factors in four-loop QCD
Roman N. Lee, Andreas von Manteuffel, Robert M. Schabinger +3
We analytically compute all four-loop QCD corrections to the photon-quark and Higgs-gluon form factors involving a closed massless fermion loop. Our calculation of non-planar verte…
