Discovery potential of h/H/A->ττ->ll 4ν

This page contains approved plots and results in the order as they appear in the CSC note. Only the CSC note contains all the relevant information and should thus be consulted if one of the plots is used.

Table 2: Cross-section in fb passing the preselection criteria. The numbers for the signal samples are given assuming tanβ=20. In the event samples marked '2μ filter' two muons are required to be present at generator level. The numbers marked with (*) were obtained using cut factorization.

Table 3: Accepted cross-section in fb for optimized cuts for m_A=130GeV and tanβ=20. The values of the cuts applied are stated for the ee/μμ (upper row) and eμ (lower row) subchannels. In case only one number is given it applies to all leptonic subchannels.

Table 4: Accepted cross-section for all Higgs boson mass hypotheses analyzed. The cross-section in fb for signal and background after all selection cuts is given (except for the cut on the mass window) for tanβ=20.

Figure 3: Invariant m_{τ τ} distribution for Higgs boson candidates with nominal masses as indicated in the plots. The distributions are shown after all selection cuts for tanβ=20. The vertical lines indicate the mass window used for calculating the signal significance.

Table 5: Effects of systematic uncertainties for different Higgs boson masses for tanβ=20. The effects of the systematic uncertainties considered are listed in percent. The total uncertainty is obtained by adding the individual contributions in quadrature.

Figure 7: The five σ discovery potential (left) and the 95% exclusion limit (right) as a function of m_A and tanβ. The solid line represents the main result of the analysis. The dashed lines indicate the discovery potential and exclusion limit including an addition 10% uncertainty on the tt cross-section. The bands represent the influence of the systematic uncertainty on the signal cross-section.

Figure 8: The discovery potential as a function of tanβ and for Higgs boson masses as indicated in the plots. The solid lines indicate the discovery potential including experimental systematic uncertainties. The dashed lines indicate the discovery potential including an additional systematic uncertainty on the tt cross-section. The bands indicate the impact of the systematic uncertainty on the signal cross-section.

Figure 9: The discovery potential as a function of m_A. The solid lines indicate the discovery potential including experimental systematic uncertainties for tanβ values as indicated in the plots. The dashed lines indicate the discovery potential including an additional systematic uncertainty on the tt cross-section of 10%. The bands indicate the impact of the systematic uncertainty on the signal cross-section.
