We compute the fragmentation functions for the production of a Higgs boson at order $\mathcal{O}(y_t^2 \alpha_s)$. Real and virtual corrections have been computed by using modern loop computation techniques. In particular, we combine the unitary cut method with the differential equation approach. We find the criteria to bring the master integrals in canonical form, so that their computation is...

Since the discovery of the Higgs boson at the Large Hadron Collider, many of its properties such as the mass and the couplings to Standard Model gauge bosons have been studied extensively and determined to a good level of accuracy. The direct measurement of the Higgs width $\Gamma_H$, however, remains elusive due to limited detector resolution. In the past it has been observed that $\Gamma_H$...

98. Towards Higgs boson production in weak boson fusion at higher orders with realistic final states

I present new results for fully differential next-to-next-to-leading-order QCD corrections to Higgs boson production in vector-boson fusion in the factorizing limit. In contrast to earlier computations of this process, decays of the Higgs boson at leading order are included.
