Description

A search for the resonant production of a heavy scalar X decaying into a Higgs boson and a new lighter scalar S, through the process X -> S(bb)H(yy), where the two photons are consistent with the Higgs boson decay, is performed. The search is conducted using 140 fb-1 of LHC Run 2 data recorded by ATLAS. The search is performed for 170 GeV <=mX <= 1000 GeV and 15 GeV <= mS <= 500 GeV. Parametrized Neural Networks are used to enhance the signal purity and to achieve continuous sensitivity in the (mX, mS) mass plane.
