Direct detection of galactic halo dark matter.

The Milky Way galaxy contains a large, spherical component which is believed to harbor a substantial amount of unseen matter. Recent observations indirectly suggest that as much as half of this "dark matter" may be in the form of old, very cool white dwarfs, the remnants of an ancient population of stars as old as the galaxy itself. We conducted a survey to find faint, cool white dwarfs with la...

WIMP direct detection and halo structure

Weakly Interacting Massive Particle (WIMP) direct detection experiments are just reaching the sensitivity required to detect Galactic dark matter in the form of neutralinos (or indeed any stable weakly interacting particle). Detection strategies and data analyses are often based on the simplifying assumption of a standard spherical, isothermal halo model, but observations and numerical simulati...

Model independent determination of the dark matter mass from direct detection experiments.

Determining the dark matter (DM) mass is of paramount importance for understanding dark matter. We present a novel parametrization of the DM speed distribution which will allow the DM mass to be accurately measured using data from weakly interacting massive particle (WIMP) direct detection experiments. Specifically, we parametrize the natural logarithm of the speed distribution as a polynomial ...

Group Signatures Without q-Assumptions

The notion of group signatures was introduced to allow group members to sign anonymously on behalf of a group. A group manager allows a user to join a group, and another will be able to open a signature to revoke its anonymity. Several schemes have already been proposed to fulfil these properties, however very few of them are proven in the standard model. Of those proven in the standard model, ...

Oblivious RAMs without Cryptographic Assumptions

We show that oblivious on-line simulation with only polylogarithmic increase in the time and space requirements is possible on a probabilistic (coin flipping) RAM without using any cryptographic assumptions. The simulation will fail with a negligible probability. If n memory locations are used, then the probability of failure is at most n− logn. Pippenger and Fischer has shown in 1979, see [11]...
