This posting is regarding the recent confirmation of the DAMA results that might be due to underlying differences in proton and neutron cross section with the dark matter particles, which reflect on the differences between Xenon and Germanium detectors
in the early days of particle physics, neutrinos were discovered as missing momentum in decay events
my question is the following: How did the current accelerators missed a dark matter product of 7GeV? possible answers i think:
1) does by any chance theory predict that these relatively low energy particles will not be created with normal particle collisions in our current multi-TeV range?
2) does the current complexity of analysis of TeV-magnitude collision products just cannot detect such missing momenta signals?
3) there are no dark matter particles in such low energy range, otherwise we would have already spotted them in particle accelerators
