Search for electroweak production of charginos and neutralinos in all hadronic final states at the CMS experiment

The results from a search for chargino-neutralino or chargino pair production via electroweak interactions are summarized. The results are based on a sample of $\sqrt{s}=13~\mathrm{TeV}$ proton-proton collisions from the LHC, recorded with the CMS detector~\cite{cms} and corresponding to an integrat...

description The results from a search for chargino-neutralino or chargino pair production via electroweak interactions are summarized. The results are based on a sample of $\sqrt{s}=13~\mathrm{TeV}$ proton-proton collisions from the LHC, recorded with the CMS detector~\cite{cms} and corresponding to an integrated luminosity of $137~\mathrm{fb}^{-1}$. The search considers final states with large missing transverse momentum and pairs of hadronically decaying bosons WW, WZ, and WH, which are identified using novel algorithms. No significant excess of events is observed relative to the expectation from the standard model. Limits at the $95\%$ confidence level are placed on the cross-section for production of mass-degenerate wino-like superpartners of SU(2) gauge bosons, $\widetilde{\chi}_{1}^{\pm}$/$\widetilde{\chi}_{2}^{0}$. In the limit of nearly-massless neutralinos $\widetilde{\chi}_{1}^{0}$, $\widetilde{\chi}_{1}^{\pm}$ and $\widetilde{\chi}_{2}^{0}$ with masses up to 870 and $960~\mathrm{GeV}$ are excluded for $\widetilde{\chi}_{2}^{0}\to\mathrm{Z}\widetilde{\chi}_{1}^{0}$ and $\widetilde{\chi}_{2}^{0}\to\mathrm{H}\widetilde{\chi}_{1}^{0}$, respectively. Interpretations for other models are also presented.
