| Abstract: A search for nonresonant pair-production of Higgs bosons (HH) with one Higgs boson decaying into four leptons and the other into a pair of b quarks is presented. The analyzed data correspond to an integrated luminosity of 137 fb$^{-1}$ of proton-proton collisions at $\sqrt{s} = $ 13 TeV collected with the CMS detector during the years 2016 to 2018. An upper limit of 30 at 95% confidence level (CL) is set on the signal strength modifier $\mu$, defined as the ratio of the observed double-Higgs boson production rate in the $\mathrm{HH \rightarrow ZZ^{*}b\bar{b} \rightarrow 4\ell b\bar{b}}$ decay channel to the standard model (SM) expectation. Possible modifications of the SM Higgs trilinear coupling are investigated and constrained to be within the observed (expected) range $-9 (-10.5) < k_{\lambda} < 14 (15.5)$ at 95% CL. | ||
