A search for bottom-type, vector-like quark pair production in dileptonic and fully hadronic final states in proton-proton collisions at $ \sqrt{s} = $ 13 TeV

CMS Collaboration

21 August 2023

Abstract: A search is described for the production of a pair of bottom-type vector-like quarks (VLQs) with a mass greater than 1000 GeV. Each VLQ decays into a b quark and a Higgs boson, a b quark and a Z boson, or a t quark and a W boson. This analysis considers both fully hadronic final states and those containing a lepton pair from a Z boson decay. The products of the hadronic Higgs, Z, or W boson decays can be resolved as two distinct jets or merged into a single jet, so the final states are separated by the number of reconstructed jets. The analysis uses data corresponding to a total integrated luminosity of 138 fb$^{-1}$ collected in proton-proton collisions at $ \sqrt{s}= $ 13 TeV by the CMS detector at the LHC from 2016 to 2018. No signal in excess of the expected background is observed, and lower limits are set on the VLQ mass at 95% confidence level. These depend on the VLQ branching fractions and are 1570 GeV and 1540 GeV for 100% B $ \rightarrow $ bH and 100% B $ \rightarrow $ bZ, respectively. For many cases, they exceed by 100 GeV or more those of previous results.

Summary

A search for bottom-type vector-like quarks (VLQs) has been presented, using data from proton-proton collisions collected by the CMS detector in 2016--2018 at $ \sqrt{s} = $ 13 TeV. Results are combined from the fully hadronic category, where each B VLQ decays into either a b quark and a Higgs boson, a b quark and a Z boson, or a t quark and a W boson, and the leptonic category, where each B VLQ decays into a b quark and either a Higgs or a Z boson, and at least one decay includes a Z boson that decays into a pair of leptons. To account for the fact that the two jets from a Higgs, Z, or W boson decay may be reconstructed separately, or may be merged into a single reconstructed jet due to a high Lorentz boost, events are separated into different jet multiplicity categories and reconstructed appropriately. Backgrounds are estimated from data and limits are set on the VLQ mass at a 95% confidence level as a function of the branching fractions $ \mathcal{B}({\mathrm{B}} \to \mathrm{b}\mathrm{H}) $, $ \mathcal{B}({\mathrm{B}} \to \mathrm{b}\mathrm{Z}) $, and $ \mathcal{B}({\mathrm{B}} \to \mathrm{t}\mathrm{W}) $. Compared to the previous CMS result [22], the limits on the B VLQ mass have been increased from 1390 to 1540 GeV and 1450 to 1500 GeV in the 100% $ {\mathrm{B}} \to \mathrm{b}\mathrm{Z} $ and $ {\mathrm{B}}\mathrm{Y} $ doublet cases, respectively, while also exceeding limits set by ATLAS at these branching fractions by 120 and 170 GeV, respectively [23,24]. These represent the current world best limits on B VLQs.
