Fully Differential Higgs Boson Production to Third Order in QCD

We present fully differential predictions for the production cross section of a Higgs boson via gluon fusion mechanism at next-to-next-to-next-to leading order (N$^3$LO) in QCD perturbation theory. To perform our calculation we apply Projection-to-Born method first time to non-factorising colorless final state LHC N$^3$LO. predict distributions two photon produced by decay and fiducial cuts on rapidities momenta. The N$^3$LO corrections these have complex features are part larger than inclusive section. Overall, observe that inclusion significantly reduces perturbative uncertainties leads stabilisation expansion.
