“…There is a worldwide effort toward the development of a large TPC (Time Projection Chamber) devoted to directional detection [40,41,42,43,44]. In the following, we exemplify our Dark Disk study by considering a MIMAClike detector corresponding to a low exposure (30 kg.year) CF 4 TPC allowing three dimensional track measurements [42].…”

Recent N-Body simulations are in favor of the presence of a co-rotating Dark Disk that might contribute significantly (10%-50%) to the local Dark Matter density. Such substructure could have dramatic effect on directional detection. Indeed, in the case of a null lag velocity, one expects an isotropic WIMP velocity distribution arising from the Dark Disk contribution, which might weaken the strong angular signature expected in directional detection. For a wide range of Dark Disk parameters, we evaluate in this Letter the effect of such dark component on the discovery potential of upcoming directional detectors. As a conclusion of our study, using only the angular distribution of nuclear recoils, we show that Dark Disk models as suggested by recent N-Body simulations will not affect significantly the Dark Matter reach of directional detection, even in extreme configurations.

NEWAGE is a direction-sensitive direct dark matter search experiment. NEWAGE uses a micro time-projection chamber with a detection volume of 31 × 31 × 41cm 3 , which is read by a macro-petterned gaseous detectors, µ-PIC. Underground measurements with the current detector, NEWAGE-0.3b , have been performed since 2013. After the first direction-sensitive limits drived from 31.6 live-days of NEWAGE-0.3b' data were published, measurements were continued and the preliminary results from an addtional 170 days of results are reported here. In order to improve the sensitivity, low α-particle emission µ − PICs are being developed. Studies on negative-ion gases are also on-going. These recent activities that aim to improve the sensitivity are also presented here.

Abstract:We discuss the relevance of directional detection experiments in the postdiscovery era and propose a method to extract the local dark matter phase space distribution from directional data. The first feature of this method is a parameterization of the dark matter distribution function in terms of integrals of motion, which can be analytically extended to infer properties of the global distribution if certain equilibrium conditions hold. The second feature of our method is a decomposition of the distribution function in moments of a model independent basis, with minimal reliance on the ansatz for its functional form. We illustrate our method using the Via Lactea II N-body simulation as well as an analytical model for the dark matter halo. We conclude that O(1000) events are necessary to measure deviations from the Standard Halo Model and constrain or measure the presence of anisotropies.
