We present a fully analytic computation of the two-loop electroweak corrections to double Higgs production in gluon fusion, mediated by light quarks. The calculation is performed using the method of differential equations, employing a large mass expansion to generate boundary functions. We implement the results in the Powheg-Box-V2 framework for phenomenological studies. The corrections to the...
We extend the Nested Soft-Collinear Subtraction Scheme to final states with any number of gluons and (anti)quarks and derive general analytical formulas for the infrared-finite NNLO QCD corrections to a generic hadron collider process with a single flavour of quarks (nf=1). We also discuss some ideas to move towards an extension with arbitrary nf.
After the discovery of the Higgs boson in 2012, the measurements of the Higgs self coupling is still a challenge for current and future experiments in particle physics. Higgs-boson pair production via gluon fusion is a loop-induced process. In order to increase the accuracy of the theoretical predictions for this process, higher-order corrections are necessary to reduce theoretical...
