Abstract: A search for the decay of a heavy Higgs boson $\mathrm{H}$ into the observed Higgs boson $\mathrm{h}$ and another Higgs boson $\mathrm{h}_{\text{S}}$ with a mass of $m_{\mathrm{h}_{\rm S}} < m_{\mathrm{H}} - m_{\mathrm{h}}$ is presented. The $\mathrm{h}$ and $\mathrm{h}_{\text{S}}$ bosons are required to decay into a pair of tau leptons and a pair of b quarks, respectively. The search uses 137 fb$^{-1}$ of proton-proton collisions collected with the CMS detector at a center-of-mass energy of 13 TeV. A mass range of 240 - 3000 GeV for $m_{\mathrm{H}}$ and 60 - 2800 GeV for $m_{\mathrm{h}_{\text{S}}}$ is covered. No signal has been observed. Therefore, 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 ranging from 125 fb (for $m_{\mathrm{H}}=$ 240 GeV) to 2.7 fb (for $m_{\mathrm{H}}=$ 3000 GeV). These limits are compared to predictions of the next-to-minimal supersymmetric extension of the standard model. | ||
