\(m_{\ell \ell }\) distribution for the NMSSM with a singlino-like LSP as found from our simulations for the processes \(p p \rightarrow \tilde{\chi }^0_2 +X\) and \(pp \rightarrow \tilde{\chi }^0_3 + Y\), where \(X \in \{\tilde{\chi }_1^\pm ,\tilde{\chi }_3^0\}\) and \(Y \in \{\tilde{\chi }_1^\pm ,\tilde{\chi }_2^0\}\), with matrix elements including up to two additional partons. Here \(\Delta m = m_{\tilde{\chi }^0_2} - m_{\tilde{\chi }^0_1}\), as for the MSSM
