The Dark Matter Search at Jaduguda Underground Science Laboratory

Abstract

The first run for the dark matter direct search experiment at Jaduguda Underground Science Laboratory is presented in this article. The experiment named InDEx; the Indian Dark matter search Experiment has been initiated with superheated emulsion detector consisting of the droplets of tetrafluoroethane ($C_2{H}_2{F}_4$). The detector ran for an effective period of 48.6 days at a threshold of 5.87 keV with an exposure of 2.47 kg-days. It is observed that the minimum sensitivity for the SI cross-section of $[7.939\pm (0.375{)}_{statistical}{(}_{-0.909}^{+1.386}{)}_{systematic}]\times 10^{-39}$ $c{m}^2$ for fluorine appears at WIMP mass of 30.67 $GeV/c^2$. The InDEx with larger exposures is under development and yet to come in near future.
