Dark Matter Accumulation near the Earth for the Long Range Forces case

TL;DR

This paper investigates how long-range forces can cause dark matter to accumulate near Earth, significantly increasing local density and analyzing implications for WIMP accumulation.

Contribution

It introduces a model for dark matter accumulation near Earth considering long-range interactions, highlighting a potential density increase over galactic levels.

Findings

Dark matter density near Earth can exceed galactic mean by over 10^5 times.

Long-range forces significantly influence dark matter accumulation.

WIMP accumulation near Earth is also enhanced by this mechanism.

Abstract

The accumulation of dark matter near the Earth is considered. We analyze the case of long range interaction forces. Additional density of the dark matter at the Earth's surface is calculated. We show that this density exceeds the mean density of the dark matter in our galaxy by more then $10^5$ times for some values of dark matter particle mass. Accumulation of WIMP's near the Earth by the same mechanism is also analyzed.
