Heavy Higgs Searches: BSM decay modes.

People Interested: Jose Miguel No, Stefania Gori, Ken Mimasu, Daniele Barducci

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 of this 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.
