ABBIENDI 2004 search for ${{\widetilde{\mathit \tau}}}{{\widetilde{\mathit \tau}}}$ production in acoplanar di-tau final states in the $183 - 208$~GeV data. See Fig.$~$15 for the dependence of the limits on ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ and for the limit at tan $\beta $=35. Under the assumption of 100\% branching ratio for ${{\widetilde{\mathit \tau}}_{{R}}}$ $\rightarrow$ ${{\mathit \tau}}$ ~${{\widetilde{\mathit \chi}}_{{1}}^{0}}$, the limit improves to 89.8~GeV for $\Delta \mathit m>$ 8$~$GeV. See Fig.~12 for the dependence of the limits on m$_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ at several values of the branching ratio and for their dependence on $\theta _{\tau }$. This limit supersedes ABBIENDI 2000G.

ACHARD 2004 search for ${{\widetilde{\mathit \tau}}}{{\widetilde{\mathit \tau}}}$ production in acoplanar di-tau final states in the $192 - 209$ GeV data. Limits on ${\mathit m}_{{{\widetilde{\mathit \tau}}_{{R}}}}$ are derived from a scan over the MSSM parameter space with universal GUT scale gaugino and scalar masses and , 1 ${}\leq{}$tan $\beta {}\leq{}$60 and $-2{}\leq{}\mu {}\leq{}$ 2 TeV. See Fig.~4 for the dependence of the limits on ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$.

ABDALLAH 2003M looked for acoplanar ditaus $\text{+}\not E$ final states at $\sqrt {s }$ = $130 - 208$ GeV. A dedicated search was made for low mass ${{\widetilde{\mathit \tau}}}$s decoupling from the ${{\mathit Z}^{0}}$. The limit assumes B( ${{\widetilde{\mathit \tau}}}$ $\rightarrow$ ${{\mathit \tau}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ ) = 100\%. See Fig.~20 for limits on the (${\mathit m}_{{{\widetilde{\mathit \tau}}}},{\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$) plane and as function of the ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$ mass and of the branching ratio. The limit in the low-mass region improves to 29.6 and 31.1 GeV for ${{\widetilde{\mathit \tau}}_{{R}}}$ and ${{\widetilde{\mathit \tau}}_{{L}}}$, respectively, at $\Delta \mathit m>$ ${\mathit m}_{{{\mathit \tau}}}$. The limit in the high-mass region improves to 84.7$~$GeV for ${{\widetilde{\mathit \tau}}_{{R}}}$ and $\Delta \mathit m>$ 15$~$GeV. These limits include and update the results of ABREU 2001 .

HEISTER 2002E looked for acoplanar ditau + $\not E_T$ final states from ${{\mathit e}^{+}}{{\mathit e}^{-}}$ interactions between 183 and 209 GeV. The mass limit assumes B( ${{\widetilde{\mathit \tau}}}$ $\rightarrow$ ${{\mathit \tau}}{{\widetilde{\mathit \chi}}_{{1}}^{0}}$ )=1. See their Fig.$~$4 for the dependence of the limit on $\Delta \mathit m$. These limits include and update the results of BARATE 2001 .

AABOUD 2018BT searched in 36.1 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 13 TeV for direct electroweak production of charginos, chargino and next-to-lightest neutralinos and sleptons in events with two or three leptons (electrons or muons), with or without jets, and large missing transverse energy. No significant excess above the Standard Model expectations is observed. Limits are set on the slepton mass up to 500 GeV for massless ${{\widetilde{\mathit \chi}}_{{1}}^{0}}$, assuming degeneracy of ${{\widetilde{\mathit e}}}$, ${{\widetilde{\mathit \mu}}}$, and ${{\widetilde{\mathit \tau}}}$ and exploiting the 2${{\mathit \ell}}$ signature, see their Figure 8(b).

KHACHATRYAN 2017L searched in about 19 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV for events with two ${{\mathit \tau}}$ (at least one decaying hadronically) and $\not E_T$. Results were interpreted to set constraints on the cross section for production of ${{\widetilde{\mathit \tau}}_{{L}}}$ pairs for ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$=1 GeV. No mass constraints are set, see their Fig. 7.

AAD 2016AA summarized and extended ATLAS searches for electroweak supersymmetry in final states containing several charged leptons, $\not E_T$, with or without hadronic jets, in 20 ${\mathrm {fb}}{}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 8 TeV. The paper reports 95$\%$ C.L. exclusion limits on the cross-section for production of ${{\widetilde{\mathit \tau}}_{{R}}}$ and ${{\widetilde{\mathit \tau}}_{{L}}}$ pairs for various ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$, using the 2 hadronic ${{\mathit \tau}}$ + $\not E_T$ analysis. The ${\mathit m}_{{{\widetilde{\mathit \tau}}_{{R/L}}}}$ = 109 GeV is excluded for ${\mathit m}_{{{\widetilde{\mathit \chi}}_{{1}}^{0}}}$ = 0 GeV, with the constraints being stronger for ${{\widetilde{\mathit \tau}}_{{R}}}$. See their Fig. 12.

AAD 2012AF searched in 2 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with two tau leptons, jets and large $\not E_T$ in a GMSB framework. No significant excess above the expected background was found and an upper limit on the visible cross section for new phenomena is set. A 95$\%$ C.L. lower limit of 32 TeV on the mGMSB breaking scale ${{\mathit \Lambda}}$ is set for ${{\mathit M}_{{mess}}}$ = 250 TeV, ${{\mathit N}_{{S}}}$ = 3, ${{\mathit \mu}}$ $>$ 0 and ${{\mathit C}_{{grav}}}$ = 1, independent of tan ${{\mathit \beta}}$.

AAD 2012AG searched in 2.05 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$ = 7 TeV for events with at least one hadronically decaying tau lepton, jets, and large $\not E_T$ in a GMSB framework. No significant excess above the expected background was found and an upper limit on the visible cross section for new phenomena is set. A 95$\%$ C.L. lower limit of 30 TeV on the mGMSB breaking scale ${{\mathit \Lambda}}$ is set for ${{\mathit M}_{{mess}}}$ = 250 TeV, ${{\mathit N}_{{S}}}$ = 3, ${{\mathit \mu}}$ $>$ 0 and ${{\mathit C}_{{grav}}}$ = 1, independent of tan ${{\mathit \beta}}$. For large values of tan ${{\mathit \beta}}$, the limit on ${{\mathit \Lambda}}$ increases to 43 TeV.

AAD 2012CM searched in 4.7 fb${}^{-1}$ of ${{\mathit p}}{{\mathit p}}$ collisions at $\sqrt {s }$=7 TeV for events with at least one tau lepton, zero or one additional light lepton (${{\mathit e}}/{{\mathit \mu}}$) jets, and large $\not E_T$ in a GMSB framework. No significant excess above the expected background was found and an upper limit on the visible cross section for new phenomena is set. A 95\% C. L. lower limit of 54 TeV on the mGMSB breaking scale ${{\mathit \Lambda}}$ is set for ${{\mathit M}_{{mess}}}$ = 250 TeV, ${{\mathit N}_{{S}}}$ = 3, ${{\mathit \mu}}$ $>$ 0 and ${{\mathit C}_{{grav}}}$ = 1, for tan ${{\mathit \beta}}$ $>$ 20. Here the ${{\widetilde{\mathit \tau}}_{{1}}}$ is the NLSP.

ABBIENDI 2006B use 600 pb${}^{-1}$ of data from $\sqrt {s }$ = $189 - 209$ GeV. They look for events from pair-produced staus in a GMSB scenario with ${{\widetilde{\mathit \tau}}}$ NLSP including prompt ${{\widetilde{\mathit \tau}}}$ decays to ditaus + $\not E$ final states, large impact parameters, kinked tracks and heavy stable charged particles. Limits on the cross-section are computed as a function of m(${{\widetilde{\mathit \tau}}}$) and the lifetime, see their Fig. 7. The limit is compared to the $\sigma \cdot{}\mathit BR{}^{2}$ from a scan over the GMSB parameter space.

ABDALLAH 2004H use data from LEP~1 and $\sqrt {s }$ = $192 - 208$~GeV. They re-use results or re-analyze the data from ABDALLAH 2003M to put limits on the parameter space of anomaly-mediated supersymmetry breaking (AMSB), which is scanned in the region 1$<{{\mathit m}}_{3/2}<$50~TeV, 0$<{{\mathit m}_{{0}}}<$1000~GeV, 1.5$<$tan ${{\mathit \beta}}<$35, both signs of ${{\mathit \mu}}$. The constraints are obtained from the searches for mass degenerate chargino and neutralino, for SM-like and invisible Higgs, for leptonically decaying charginos and from the limit on non-SM ${{\mathit Z}}$ width of 3.2~MeV. The limit is for ${\mathit m}_{{{\mathit t}}}$ = 174.3~GeV (see Table 2 for other ${\mathit m}_{{{\mathit t}}}$ values). The limit improves to 75 GeV for ${{\mathit \mu}}$ $<$ 0.
