# Direct Detections of Dark Matter in the Presence of Non-standard Neutrino Interactions

## TL;DR

This paper examines how non-standard neutrino interactions affect the sensitivity limits of dark matter direct detection experiments, revealing significant modifications to neutrino floors depending on the type of NSI involved.

## Contribution

It derives new neutrino floors considering current bounds on NSIs, highlighting their impact on dark matter detection sensitivity and proposing combined experimental approaches.

## Key findings

- Neutrino floors can be increased by up to 20% due to vector and scalar NSIs.
- Axial-vector and tensor NSIs have negligible impact on neutrino floors.
- Combining detection experiments can help uncover new physics.

## Abstract

In this paper we investigate impacts of non-standard neutrino interactions (NSIs) to the limitations on the discovery potential of dark matter in direct detection experiments. New neutrino floors are derived taking into account current upper bounds on the effective couplings of various NSIs. Our study shows that the neutrino floors of the standard model neutral current interactions can be significantly changed in the presence of vector-current NSI and scalar-current NSI, and the neutrino floors can be raised up to about ${\cal O}(20\%)$ in the presence of pseudo-scalar-current NSI, and there are almost no impacts to the neutrino floors from the axial-vector NSI and the tensor NSI. We suggest combining the dark matter direct detection experiments with the coherent elastic neutrino nucleus scattering experiments to hunt for new physics behind the signal of nuclear recoil in the future.
