Light Relic Neutralinos
A. Bottino, N. Fornengo, S. Scopel
The relic abundance and the scalar cross-section off nucleon for light neutralinos (of mass below about 45 GeV) are evaluated in an effective MSSM model without GUT-inspired relati…
Light Neutralinos as Dark Matter in the Unconstrained Minimal Supersymmetric Standard Model
A. Gabutti, M. Olechowski, S. Cooper +2
The allowed parameter space for the lightest neutralino as the dark matter is explored using the Minimal Supersymmetric Standard Model as the low-energy effective theory without fu…
Detection of nuclear recoils in prototype dark matter detectors, made from Al, Sn and Zn Superheated Superconducting Granules
M. Abplanalp, C. Berger, G. Czapek +12
This work is part of an ongoing project to develop a Superheated Superconducting Granule (SSG) detector for cold dark matter and neutrinos. The response of SSG devices to nuclear r…
Quasiparticle and phonon propagation in superheated superconducting granules after nuclear recoils
A. Gabutti
The propagation of the excess of quasiparticles and phonons produced by a nuclear recoil inside Sn and Zn superheated superconducting granules will be discussed. The decay towards…
Nuclear recoil measurements in Superheated Superconducting Granule detectors
K. Schmiemann
The response of Superheated Superconducting Granule (SSG) devices to nuclear recoils has been explored by irradiating SSG detectors with a 70MeV neutron beam. In the past we ha…
Feasibility study of a Superheated Superconducting Granule detector for cold dark matter search
A. Gabutti
The presented results are part of a feasibility study of a Super- heated Superconducting Granule (SSG) device for weakly interacting massive particles (WIMPs) detection. The sensit…
