In extensions of the SM Higgs sector (and more generally) the dominant decay modes of heavy Higgses may not be the “traditional” ones (VV, tt, bb), but instead H → X1 X1, H → X1 X2 and/or H → X1 SM (with X1, X2 being BSM states, e.g. new scalars/pseudoscalars). Depending on the dominant decay of X1, X2, these could constitute the discovery mode for both H and X1,X2.

A concrete example is H → A A → 4 b, which can be viewed as a generalization of resonant di-Higgs searches in the 4 b final state leaving the mass of the A state free. This project constitutes a feasibility study of this channel in the mH, mA, Width_H parameter space
