# $N$-jettiness subtractions for $gg→H$ at subleading power

Iain W. Stewart, Frank J. Tackmann, Hua Xing Zhu, Lorena Rothen, Ian Moult
$N$-jettiness subtractions provide a general approach for performing fully-differential next-to-next-to-leading order (NNLO) calculations. Since they are based on the physical resolution variable $N$-jettiness, ${\mathcal{T}}_{N}$, subleading power corrections in $τ={\mathcal{T}}_{N}/Q$, with $Q$ a ...
