NEMESIS setup for Indirect Detection of WIMPs

We summarize the evidence for DM-like anomalies in neutron multiplicity spectra collected underground with Pb targets by three independent experiments: NEMESIS (at 210 m.w.e.) NMDS 583 m.w.e.), and ZEPLIN-II 2850 m.w.e.). A new analysis shows small but persistent at high multiplicities. Adjusted differences detection efficiencies, positions of are consistent between systems. Also, intensities match when corrected acquisition time estimated efficiency. While measurements inconclusive analyzed separately, together, they exclude a statistical fluke to better than one million. To prove existence above 5-sigma discovery threshold, we propose upgrade current setup. The concept critical components experiment described. upgraded setup would already acquire needed data sample during first year operation. Additional information, vital physics interpretation analysis, will be obtained Cu target.
