Focused Session: Neutrino Floor
- Kentaro Miuchi (Kobe University)
WIMP detectors in the 2020's will approach the sensitivity at which
scatters of natural neutrinos will create a background sufficient to
obscure the WIMP recoil signal. This is the so-called "Neutrino
Floor". This talk will discuss the nature of the neutrino floor and
the motivations to get to it, and to potentially go beyond it.
I will explain why the neutrino floor exists from a statistical perspective and then discuss what kind of information we need from an experimental search to be able to subtract the neutrino background.
In the standard methodology for the WIMP search detect recoiled nuclei due to elastic scattering with that, the neutrino should become background to be not able to avoid. If not detect significant signals or just few events detected before neutrino floor, more reliable search to confirm those are the signals due to WIMP or new information to distinguish the WIMP signals from neutrino...
