$H \rightarrow b\overline{b}j$ at Next-to-Next-to-Leading Order Accuracy

Understand

We present the calculation of the decay $H \rightarrow b\overline{b}j$ at next-to-next-to-leading order (NNLO) accuracy.

• We consider contributions in which the Higgs boson couples directly to bottom quarks, i.e.
• our predictions are accurate to order $\mathcal{O}(\alpha_s^3 y_b^2)$ .
• We calculate the various components needed to construct the NNLO contribution, including an independent calculation of the two-loop amplitudes.
