Novel trigger, reconstruction, and machine-learning techniques were developed for and employed in this search. After all selections, the observations are consistent with the background predictions. Limits are presented on the branching fraction of the Higgs boson to long-lived particles that subsequently decay to quark pairs or tau lepton pairs. Up to a factor of 10 improvement is achieved over previous limits for models with long-lived particle masses smaller than $60~\\mathrm{GeV}$ and proper decay lengths smaller than $1~\\mathrm{m}$. The first constraints are placed on the fraternal twin Higgs and folded supersymmetry models, where the lower bounds on the top quark partner mass reach up to $350~\\mathrm{GeV}$ for the fraternal twin Higgs model and $250~\\mathrm{GeV}$ for the folded supersymmetry model.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t1","@type":"Dataset","description":"The predicted background yields and the number of observed events for the data with $g_{\\mathrm{prompt-veto}}>0.985$, shown for different bins of...","name":"Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t2","@type":"Dataset","description":"The 95% CL upper limits on the branching fraction $\\mathcal{B}(\\mathrm{H \\to SS})$ with $\\mathrm{S \\to b\\overline{b}}$ deacy, for different LLP...","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t3","@type":"Dataset","description":"The 95% CL upper limits on the branching fraction $\\mathcal{B}(\\mathrm{H \\to SS})$ with $\\mathrm{S \\to d\\overline{d}}$ decay, for different LLP...","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t4","@type":"Dataset","description":"The 95% CL upper limits on the branching fraction $\\mathcal{B}(\\mathrm{H \\to SS})$ with $\\mathrm{S}\\to\\tau\\tau$ decay, for different LLP masses $m_{\\mathrm{S}}$...","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t5","@type":"Dataset","description":"The 95% CL limits on the LLP mass $m_{\\mathrm{S}}$ for different proper decay lengths $c\\tau_{0}$ assuming a branching fraction of...","name":"Figure 6a"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t6","@type":"Dataset","description":"The 95% CL limits on the LLP mass $m_{\\mathrm{S}}$ for different proper decay lengths $c\\tau_{0}$ assuming a branching fraction of...","name":"Figure 6b"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t7","@type":"Dataset","description":"The 95% CL limits on the dark-sector top quark partner mass $m_{T}$ for different hidden glueball masses $m_{0}$ in the...","name":"Figure 7a"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t8","@type":"Dataset","description":"The 95% CL limits on the dark-sector top quark partner mass $m_{T}$ for different hidden glueball masses $m_{0}$ in the...","name":"Figure 7b"},{"@id":"https://doi.org/10.17182/hepdata.153947.v2/t9","@type":"Dataset","description":"The 95% CL upper limits on $\\sigma(\\mathrm{pp}\\to\\mathrm{Z}')\\mathcal{B}(\\mathrm{Z}'\\to\\mathrm{Q_{dark}\\overline{Q}_{dark}})$ when the dark pion mass $m_{\\pi_{\\mathrm{dark}}}$ is $20~\\mathrm{GeV}$.
