RT Journal Article T1 Coupling of tṫ over-bar and γγ with a strongly interacting Electroweak Symmetry Breaking Sector A1 Delgado López, Rafael AB We report the coupling of an external γγ or t(t¯) state to a strongly interacting EWSBS satisfying unitarity. We exploit perturbation theory for those coupling of the external state, whereas the EWSBS is taken as strongly interacting. We use a modified version of the IAM unitarization procedure to model such a strongly interacting regime. The matrix elements VLVL → V_(L)V_(L), V_(L)V_(L) ↔ hh, hh → hh, V_(L)V_(L) ↔ {γγ, tt¯}, and hh ↔ {γγ, tt¯} are all computed to NLO in perturbation theory with the Nonlinear Effective Field Theory of the EWSBS, within the Equivalence Theorem. This allows us to describe resonances of the electroweak sector that may be found at the LHC and their effect on other channels such as γγ or tt¯ where they may be discovered.
