Quantifying galactic propagation uncertainty in WIMP dark matter search with AMS01 Z=-1 spectrum
A search for a WIMP dark matter annihilation signal is carried out in the AMS01 negatively charged (Z=-I) particle spectrum, following a set of supersymmetric benchmark scenarios in the mSUGRA framework. The result is consistent with no dark matter, assuming a smooth isothermal distribution of dark …

An assessment of the sensitivity of a low pressure time projection chamber to the direction of WIMP-induced nuclear recoils/
Direct directional detection of dark matter could provide an unambiguous observation of dark matter due to the predicted directional anisotropy of dark matter particles in the galactic reference frame. The Dark Matter Time Projection Chamber (DMTPC) collaboration develops TPCs with optical readout …

An analysis of the sensitivity of a low pressure time projection chamber to a directional anisotropy due to WIMP interactions
The Dark Matter Time Projection Chamber (DMTPC) collaboration is a dark matter direct detection effort which develops TPCs to observe and reconstruct nuclear recoils generated by incident particles. If some of these recoils are the result of dark matter interactions, we can in theory observe an …
