@article{Liu2021RadiativeQJ, title={Radiative quark jet function with an external gluon}, author={Ze Long Liu and Matthias Neubert and Marvin Schnubel and Xing Wang}, journal={Journal of High Energy Physics}, year={2021}, volume={2022} }

Factorization theorems in soft-collinear effective theory at subleading order in power counting involve “radiative jet functions”, defined in terms of matrix elements of hard-collinear fields with a soft momentum emitted from inside the jet. Of particular importance are the radiative quark jet functions with an external photon or gluon, which arise e.g. in the factorization theorems for the Higgs-boson amplitudes h → γγ, h → gg and gg → h induced by light-quark loops. While the photon case has…
