摘要

隐藏阈值技术通过强子对撞机中两个或多个同时发生的新物理(NP)衰变来重建NP质量。我们展示了这在几个MSSM例子中如何实现:χ~i0χ~j0e+eμ+μχ~10χ~10\widetilde{\chi}_{i}^0 \widetilde{\chi}_{j}^0 \to e^+ e^- \mu^+ \mu^- \widetilde{\chi}_{1}^0 \widetilde{\chi}_{1}^0i,j=2,3,4i,j=2,3,4)和χ~1±χ~20W±(±ν)χ~10 Z0(±)χ~10{\widetilde\chi_1}^\pm {\widetilde\chi_2}^0 \to {W^\pm}^*(\to \ell^\pm \nu) {\widetilde\chi_1}^0 ~ {Z^0}^*(\to \ell^\pm \ell^\mp) {\widetilde\chi_1}^0
