title: "Table 4" of "A search for $t\bar{t}$ resonances using lepton-plus-jets events in proton-proton collisions at $\sqrt{s} = 8$ TeV with the ATLAS detector"

description: Selection efficiency x Acceptance for a spin-0 resonance.
description: A search for new particles that decay into top quark pairs is reported. The search is performed with the ATLAS experiment at the LHC using an integrated luminosity of 20.3 fb-1 of proton-proton collision data collected at a centre-of-mass energy of $\sqrt{s}= 8$ TeV. The lepton-plus-jets final state is used, where the top pair decays to $W^+bW^-\bar{b}$, with one W boson decaying leptonically and the other hadronically. The invariant mass spectrum of top quark pairs is examined for local excesses or deficits that are inconsistent with the Standard Model predictions. No evidence for a top quark pair resonance is found, and 95% confidence-level limits on the production rate are determined for massive states in benchmark models. The upper limits on the cross-section times branching ratio of a narrow Z' boson decaying to top pairs range from 4.2 pb to 0.03 pb for resonance masses from 0.4 TeV to 3.0 TeV. A narrow leptophobic topcolour Z' boson with mass below 1.8 TeV is excluded. Upper limits are set on the cross-section times branching ratio for a broad colour-octet resonance with $\Gamma$/m= 15% decaying to $t\bar{t}$. These range from 2.5 pb to 0.03 pb for masses from 0.4 TeV to 3.0 TeV. A Kaluza-Klein excitation of the gluon in a Randall-Sundrum model is excluded for masses below 2.2 TeV.

title: "Table 1" of "Search for neutral MSSM Higgs bosons decaying into a pair of bottom quarks"

description: Expected and observed 95% CL upper limits on sigma(pp-&gt;b+ H(MSSM)+X) * B(H(MSSM) -&gt; bb) in pb as a function of m(H(MSSM)), where H(MSSM) denotes a generic Higgs-like state, as obtained from the 8 TeV data.
description: CERN-LHC. The analysis searches for neutral Higgs bosons which decay into a bb quark pair and are produced in
association with at least one additional b quark. This signature is sensitive to the Higgs sector of the minimal supersymmetric standard model (MSSM) with large values of the parameter tan(beta). The analysis is based on data from proton-proton collisions at a center-of-mass energy of 8 TeV collected with the CMS detectorat the LHC, corresponding to an integrated luminosity of 19.7 fb-1. The results are combined with a previous analysis based on 7 TeV data. No signal is observed. The tables give upper limits on the cross section times branching fraction for Higgs bosons with masses up to 900 GeV, and upper limits for the MSSM parameter tan(beta) as function of the mass of the pseudoscalar MSSM Higgs boson A within different MSSM benchmark scenarios.

Only selected tables are displayed here. Please see the full paper for interpretations in other MSSM benchmark scenarios.
