Abstract: (Springer)

A search for a heavy Higgs boson H decaying into the observed Higgs boson h with a mass of 125 GeV and another Higgs boson h

_{S}

is presented. The h and h

_{S}

bosons are required to decay into a pair of tau leptons and a pair of b quarks, respectively. The search uses a sample of proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 137 fb

^{−1}

. Mass ranges of 240–3000 GeV for m

_{H}

and 60–2800 GeV for

{m}_{{\mathrm{h}}_{\mathrm{S}}}

are explored in the search. No signal has been observed. Model independent 95% confidence level upper limits on the product of the production cross section and the branching fractions of the signal process are set with a sensitivity ranging from 125 fb (for m

_{H}

= 240 GeV) to 2.7 fb (for m

_{H}

= 1000 GeV). These limits are compared to maximally allowed products of the production cross section and the branching fractions of the signal process in the next-to-minimal supersymmetric extension of the standard model.[graphic not available: see fulltext]
