Annual and Diurnal Modulations of the Angular Distribution of the 3-D WIMP Velocity Observed at an Underground Laboratory

Abstract

In this article, I present our (Monte Carlo) simulation results of the angular distribution of the 3-dimensional WIMP velocity, in particular, a possible "annual" modulation and the diurnal modulation proposed in literature, for different underground laboratories.
