Search for dark matter with the ATLAS detector

Figures & data

Figure 1. ATLAS limits on dark matter production with a high transverse momentum photon in the final state, in the framework of the EFT for operators D5 (top left), D8 (top right) and D9 (bottom left). Bottom right: Upper limits on the WIMP–nucleon cross-section in the spin-dependent and spin-independent cases inferred from the high transverse momentum photon results.

Figure 2. Left: ATLAS limits on the coupling $\sqrt{g_f{g}_{\mathit{\chi }}}$ in a simplified model where dark matter production at LHC is mediated by a vector boson of mass $m_V$. Right: Upper limits on $M^{\ast }$ when the high transverse momentum photon signal region is used to set limits on an effective theory with a $\mathit{\gamma }\mathit{\gamma }\mathit{\chi }\mathit{\chi }$ vertex.

Figure 3. Summary of ATLAS upper limits on WIMP–nucleon cross-section for spin-independent (spin-dependent) interactions on the left (right) panel obtained from the mono-$W/Z$ leptonic and hadronic searches.

Figure 4. Left: ATLAS upper limits on the visible production cross-section in the resonant production mode for top+dark matter for different values of the resonant effective coupling strength $a_{res}$. Right: ATLAS upper limits on the visible production cross-section in the non-resonant production mode for top+dark matter, for different values of the non-resonant effective coupling strength $a_{non\text{-}res}$.

Figure 5. ATLAS upper limits on the WIMP–nucleon cross-sections in the spin-independent case via the D1 EFT operator (left) and in the spin-dependent case via the D9 EFT operator (right), as function of the WIMP mass $m_{\mathit{\chi }}$.
