Dark matter and nonlocality of spacetime

TL;DR

This paper discusses a dark matter candidate called O$f$DM linked to spacetime nonlocality, highlighting its unique predictive nature and implications for detection efforts.

Contribution

It introduces the O$f$DM model connecting dark matter to spacetime nonlocality, emphasizing its minimal parameters and testable predictions.

Findings

O$f$DM predicts all direct detection experiments will fail.

The model has only one free parameter.

It offers new avenues for testing dark matter hypotheses.

Abstract

In this letter, we review a candidate for dark matter, known as O$f$DM, and explain how it relates to spacetime nonlocality. This connection provides a physical interpretation for why O$f$DM exists. Given the state of direct and indirect searches for dark matter, O$f$DM model would be an important candidate to consider, since it predicts all direct searches would fail to detect DM. The model has only one free parameter and in this regard, it is highly predictive. We review a few avenues to test this model.
