Description
BSM in the process $VV\rightarrow H^* \rightarrow VV$ can arise in two ways: As an effective extension of a composite Higgs at low energies or by a deviation hinting at a close-by resonance at high energies. It is thus necessary to control the standard model in these regions to high precision. We present novel standard model backgrounds, alongside lattice estimates for them, which arise from a complete treatment of gauge invariance in the standard model. We will give a detailed discussion of the origin of these corrections. At low energies, we provide estimates of the effective standard model size of the Higgs, which is of order $(40 ~\mathrm{GeV})^{-1}$. At high energies, we give first results for the PDFs for the weak sector, which need to be taken into account for an adequate estimate of the cross section.
