Hitting the neutrino floor will be a new window into how these particles work, but if WIMPs
live beneath that sensitivity level, the sea of neutrinos we expect to detect will complicate the continuing search for dark matter.
Scientists working on the PICO experiment had to also make sure, by calibrating the heat and pressure in the bubble chamber, that the detector was sensitive only to WIMPs
and not other background signals, such as those from electrons and gamma rays.
A massive superpartner should have precisely the properties needed to account for the dark matter in space; it would interact only weakly with ordinary matter, inspiring the nickname of WIMP
(weakly interacting massive particle).
A rise in the positron energy followed by a dramatic fall is what would be expected from Wimp
Though dark matter exerts a tangible force on the galaxy as a whole, individual WIMPs
have proved far more difficult to detect.
Every so often, a Wimp
will bounce off an atom in the detector, creating a very tiny little signal.
