### Description

Abstract: We investigate a prototype lattice BSM model with pNGB Higgs by combining 4 light (massless) flavors and 8 heavy flavors. In the infrared, the SU(4) chiral symmetry is spontaneously broken, while in the ultraviolet it exhibits the properties of the $N_f=12$ conformal fixed point. The running coupling of this system walks" and the energy range of walking can be tuned by the mass of the heavy flavors. At the same time, renormalization group considerations predict the spectrum of such a system to show hyperscaling i.e. hadron masses in units of $F_\pi$ are independent of the heavy mass. Hyperscaling is present for bound states made-up of light, heavy, or heavy and light flavors. This observation is supported by numerical observations and makes the model strongly predictive.
