\begin{document}$X^\pm$\end{document}) through the process of \begin{document}$pp\to X^+X^-\to W^+W^- X^0 X^0$\end{document}, where \begin{document}$X^0$\end{document} denotes the dark matter candidate. The hadronic decay mode of the W boson is considered to maximize the number of signal events. When the mass split between \begin{document}$X^\pm$\end{document} and \begin{document}$X^0$\end{document} is large, the jet-substructure technique must be utilized to analyze the boosted W-jet. Here, we consider the process of chargino pair production at the LHC, i.e., \begin{document}$pp\to \chi_1^+\chi^-_1 \to W^+W^-\chi_1^0\chi_1^0$\end{document}, and demonstrate that the proposed signature is able to cover more parameter space of \begin{document}$m_{\chi_1^\pm}$\end{document} and \begin{document}$m_{\chi_1^0}$\end{document} than the conventional signature of multiple leptons plus missing energy. More importantly, the signature of interest is not sensitive to the spin of heavy resonances."> New physics and two boosted <i>W</i>-jets plus missing energy -
