Abstract [en]

A study for the search for vector-like quarks and a new pseudo Nambu-Goldstone boson(pNGB) scalar at the LHC running at $\sqrt{s} = 13$ TeV is presented. A model based on the composite Higgs model in which the Higgs boson emerges as a composite pNGB together with a new pNGB $\eta$ is considered. Simulations are made on the modelshowing a low ratio between signal to background indicating no significance and a low discovery potential. However, further studies are needed as more channels should be investigated. Moreover, a more sophisticated analysis is needed to properly reject the background and for a more thorough statistical analysis. Even so, results still show potential in the search as there do exist distinct differences between signal and SM background.
