Diagram corresponding to the SUSY simplified model targeted by this analysis, \ie, chargino-neutralino production, with the chargino decaying to a $\PW$ boson and an LSP, while the heavier neutralino decays to a Higgs boson and an LSP.

Distributions in \mbb (top left), \ETm (top right), \mt (bottom left), and \mct (bottom right) for signal and background events in simulation after the preselection. The \ETm, \mt, and \mct distributions are shown after the $90<\mbb<150$\GeV requirement. Expected signal distributions are also overlaid as open histograms for various mass points, with the signal cross section scaled up by a factor of 50 for display purposes. The legend entries for signal give the masses $(m_{\chipmo}, m_{\lsp})$ in \GeV and the factor by which the signal cross section has been scaled.

(left) Distribution in \mbb in \crdl\ after the preselection level cuts defined in Table~\ref{tab:crsel}, comparing data to MC simulation. (right) Distribution in \mbb in \crmbb\ after preselection level cuts defined in Table~\ref{tab:crsel}. The signal region range of $90 \leq \mbb \leq 150$\GeV has been removed from the plot.

Distributions in \mbb after all signal region kinematic requirements for the two exclusive \ETm bins (left: $125 \leq \ETm < 200$\GeV, right: $\ETm \geq 200$\GeV). The signal region is $90 \leq \mbb \leq 150$\GeV. The hatched band shows the total uncertainty in the background prediction, including statistical and systematic components. The expected signal distribution for a reference SUSY model is overlaid as an open histogram, and the legend (on the last line) gives the masses as $(m_{\chipmo}, m_{\lsp})$ in \GeV.

(left) Cross section exclusion limits at the 95\% CL are shown for $\chipmo\chitn\to\PW^{\pm}\PH\lsp\lsp$ as a function of $m_{\chipmo}$, assuming $m_{\lsp} = 1$\GeV. The solid black line and points represent the observed exclusion. The dashed black line represents the expected exclusion, while the green and yellow bands indicate the $\pm$1 and 2 standard deviation (s.d.) uncertainties in the expected limit. The magenta line shows the theoretical cross section with its uncertainty. (right) Exclusion limits at the 95\% CL in the plane of $m_{\chipmo}$ and $m_{\lsp}$. The area below the thick black (dashed red) curve represents the observed (expected) exclusion region. The thin dashed red line indicates the +1 s.d.$_{\text{exp.}}$ experimental uncertainty. The -1 s.d.$_{\text{exp.}}$ line does not appear as no mass points would be excluded in that case. The thin black lines show the effect of the theoretical uncertainties ($\pm$1 s.d.$_{\text{theory}}$) on the signal cross section.
