Exclusion limits on higgsino pair production divided by the theory cross-section.The results of the low-mass analysis are used below m(higgsino) = 300 GeV, while those of the high-mass analysis are used above. The figure shows the observed and expected 95% upper limits on the higgsino pair production cross-section as a function of m(higgsino).

Observed and expected 95% limits in the m(higgsino) vs BR(higgsino to higgs+gravitino) plane. The regions above the lines are excluded by the analyses.

Particle-level acceptance for the low-mass discovery signal regions low-SR-MET0-meff440 and low-SR-MET150-meff440, shown as a function of higgsino mass. The acceptance is defined as the fraction of signal events passing the particle-level event selection that emulates the detector-level selection. The acceptance calculation considers only those signal events where both higgsinos decay to Higgs bosons that subsequently both decay to b-quarks.

The experimental efficiency of the low-mass analysis, for the two discovery signal regions low-SR-MET0-meff440 and low-SR-MET150-meff440, as a function of higgsino mass. The experimental efficiency is defined as the number of events passing the detector-level event selection divided by the number of events passing the event selection for a perfect detector. The denominator is obtained by implementing particle-level event selection that emulate the detector-level selection. Such particle-level selection is not applied on the numerator.

Observed ST distribution in the tau-tau signal region, compared to the expected SM background contributions. The distribution labeled electroweak contains the contributions from W+jets, Z+jets, and diboson processes. The signal distributions for single-leptoquark (LQ) production with mass 700 GeV are overlaid to illustrate the sensitivity. For the signal normalization, lambda = 1 and beta = 1 are assumed. The background uncertainty bands represent the sum in quadrature of statistical and systematic uncertainties obtained from the fit. The lower panels show the ratio between the observed and expected events in each bin. In all plots, the horizontal and vertical error bars on the data points represent the bin widths and the Poisson uncertainties, respectively.

The covariance matrix of the bin contents of the background fit. em stands for e-mu channel, et for e-tau channel, mt for mu-tau channel, and tt for tau-tau channel. The numbers indicate the bin number in each final state.

Observed (black solid) and expected (black dotted) limits at 95% confidence level on the product of cross section (sigma) and branching fraction beta, obtained from the combination of the e-tau, mu-tau, and tau-tau signal regions, as well as from the emu control region, as a function of the leptoquark (LQ) mass. The green and yellow bands represent the one and two standard deviation uncertainties in the expected limits. The theory prediction is indicated by the blue solid line, together with systematic uncertainties due to the choice of PDF and renormalization and factorization scales, indicated by the blue band. For generator-level cuts, please refer to the resource.

Expected and observed exclusion limits at 95% confidence level on the Yukawa coupling (lambda) at the leptoquark(LQ)-lepton-quark vertex, as a function of the LQ mass. A unit branching fraction beta of the LQ to a tau lepton and a bottom quark is assumed. The orange vertical line indicates the limit obtained from a search for pair-produced LQs decaying to lepton-tau-bb. The left-hand side of the dotted (solid) line shows the expected (observed) exclusion region for the present analysis. The gray band shows +/- 1 standard deviations of the expected exclusion limit. The region with diagonal blue shading shows the parameter space preferred by one of the models proposed to explain anomalies observed in B physics.
