Description

Mass-split models are governed by a nearby conformal infrared fixed point and therefore feature by construction a large separation of scales. This makes them attractive candidates to explore beyond the standard model scenarios describing the Higgs boson as a composite particle. We report updates on our investigation based on an SU(3) gauge theory with four light and six heavy flavors in the fundamental representation. Using ratios of light over heavy flavor masses from 1 down to 0.08, we demonstrate the presence of conformal hyperscaling, explore the validity of dilaton chiral perturbation theory (dChPT) as an effective theory describing our model, and determine the anomalous mass dimension.
