A model-independent approach to parametrizing heavy triplet resonances.
Realistic composite Higgs models predict multiple spin-1 resonances.
Abstract
Spin-1 resonances are naturally present in composite Higgs frameworks. We first review a model independent approach to parametrize a single additional heavy triplet and then we consider more realistic models arising in composite Higgs scenarios where a larger number of spin-1 resonances is expected. In these cases, finite width and interference effects can heavily affect the bounds extracted from the data.
