The phenomenologically viable region of parameter space, where the black area shows points that satisfy the WMAP bounds on relic density, and the gray area shows points where the relic density is lower than observed, but satisfies all other constraints.Reuse & Permissions

Figure 2

The causes of data point exclusion in the parameter space scan is shown in this plot. The viable region shown in gray is surrounded by three types of exclusion zones: too small or tachyonic sparticle masses are responsible for the exclusion of points in the region labeled “sparticle masses,” relic density higher than the upper WMAP bound excludes points in the region labeled “relic density,” and a stau LSP is responsible for excluding points in the region labeled “LSP.”Reuse & Permissions

Comparison between $\mathtt{D}\mathtt{e}\mathtt{l}\mathtt{p}\mathtt{h}\mathtt{e}\mathtt{s}$ and ATLAS 95% exclusion limits in the $m_0-m_{1/2}$ plane, for the signal regions R1, R2, R3, R4, and RHM defined in Table . In the combined limit plot, the ATLAS limit is obtained using the ATLAS statistical combination, while the $\mathtt{D}\mathtt{e}\mathtt{l}\mathtt{p}\mathtt{h}\mathtt{e}\mathtt{s}$ limit is obtained by taking the union of the $\mathtt{D}\mathtt{e}\mathtt{l}\mathtt{p}\mathtt{h}\mathtt{e}\mathtt{s}$ limits for each signal region.Reuse & Permissions

Figure 4

$\sigma \times A\times ϵ$ values for stochastic SUSY points, as obtained using the simulation code detailed in the text, for ATLAS signal regions R1, R2, R3, and R4. The acceptable region of stochastic supersymmetry parameter space can be found by referring to the ATLAS limits shown in Table . Points on the graphs above with values exceeding those limits are excluded. For example, the limit for signal region R1 is 22 fb. All stochastic superspace points with $\sigma \times A\times ϵ$ larger than 22 fb are ruled out, in this case $\xi \gtrsim -850\mathrm{GeV}$, represented by the region to the right of the light (blue) color. Correspondingly, the limit for R2 is 25 fb, excluding $\xi \gtrsim -800\mathrm{GeV}$ in the region to the right of the light (blue) color. The limit for R3 is 429 fb, which does not exclude any stochastic superspace points. R4 has a limit of 27 fb, which excludes $\xi \gtrsim -750\mathrm{GeV}$ in the region to the right of the (green) colored squares.Reuse & Permissions

Figure 5

$\sigma \times A\times ϵ$ values for stochastic SUSY points for ATLAS signal region RHM. The ATLAS limit for this signal region is 17 fb, which excludes stochastic superspace points with $\xi \gtrsim -700\mathrm{GeV}$ in the region to the right of the light (green) color.Reuse & Permissions
