Description
We study the one-loop corrections to Vector Boson Scattering within the framework of effective theories. We focus our attention on fermion-loop corrections which scale like $\mathcal{O}(s/v^4)$ in the Higgs Effective Field Theory (HEFT). Although this dependency is formally suppressed for $s \rightarrow \infty$ with respect to that from boson loops, the large top mass can lead to a numerical competition between fermion and boson loops at intermediate energies of the order of a few TeV. For the study of these fermion effects we have calculated loops of top and bottom quarks in $W^+W^- \rightarrow W^+W^−$ elastic scattering and compared it to the loop contributions from purely bosonic loops.
