Principles and applications of a neutral-current detector for neutrino physics and astronomy

The soft supersymmetry-breaking Lagrangian: theory and applications

“…the reviews [459,460,461,462]). Direct detection of WIMPs can be accomplished through elastic scattering off a nucleus in a crystal [463,464,465,466]. The recoil energy is then measured by a variety of means: scintillation detection, cryogenic detection of phonons (usually relying on superconductor transitions), ionization detection, or some combination thereof.…”

“…The cryogenic technique has been proposed in the early 80's by Drukier & Stodolsky [38] for the detection of cosmic neutrinos. The scattering media in this type of detectors is the liquid Xenon (A Xe 131) and the recoil ionization can be detected by scintillation and/or charge collection.…”

A novel source of tagged low-energy nuclear recoils

“…(1,2) and verifying it has a large branching ratio to the ground state. Using only γ's emitted during relaxation to the ground state is important in reducing background for two reasons.…”

“…Of the reported measurements only two [11,12], have probed recoils below one keV, both in Ge. This largely unexplored energy range is the most important to CNS searches [2,13,14]. Moreover, though the energy domain below a few keV is currently inaccessible in most current WIMP searches, an improved understanding of detector sensitivity in this domain could have significant benefits for setting exclusion limits on WIMPs [15,16].…”

“…LLNL-JRNL-473493 PACS numbers: 95.35.+d, 95.55. Vj,25.20.Dc Direct WIMP dark matter [1] and coherent neutrinonucleus scatter (CNS) [2,3] searches attempt to detect WIMPs and neutrinos respectively by measuring the energy they deposit when scattering off nuclei in a detector. Understanding the way recoiling nuclei distribute energy between scintillation, ionization, and thermal motion as a function of recoil energy is required to define the sensitivity of these rare event detectors.…”
