Description
We present the calculation of the next-to-leading order corrections for Higgs+jet production at the Large Hadron Collider, that arise from the Higgs trilinear self-coupling ($\lambda_{HHH}$).
We use the method of large top-quark mass expansion to tackle the challenging two-loop virtual amplitude, and apply the Pad\'{e} approximation to extend the region of convergence of this expansion.
We find that the $\lambda_{HHH}$-related corrections amount to $0.66\%$ for the total cross section. For the invariant mass distribution and Higgs boson transverse momentum distribution, the corrections are mostly in the range $0.5\% \sim 0.7\%$. Our results can be used to set extra constraints on $\lambda_{HHH}$ from the experimental data.
