# A Time Projection Chamber to Search for Feebly Interacting Bosons via Proton Induced Nuclear Reactions

## TL;DR

This paper proposes a novel Time Projection Chamber detector to search for feebly-interacting bosons, including the X17, offering significantly increased sensitivity and setting new limits in the 5-25 MeV mass range.

## Contribution

It introduces a new TPC design that enhances detection sensitivity for feebly-interacting bosons in nuclear reactions, surpassing previous experiments like ATOMKI.

## Key findings

- 200 times greater sensitivity than ATOMKI
- Provides world-leading limits on feebly-interacting bosons
- Focuses on bosons in the 5-25 MeV mass range

## Abstract

We propose a new Time Projection Chamber particle detector (TPC) to search for the existence of feebly-interacting bosons and to investigate the existence of the X17 boson, proposed by the ATOMKI group to explain anomalous results in the angular distributions of electron-positron pairs created in proton-induced nuclear reactions. Our design will provide 200 times greater sensitivity than ATOMKI and the program of research will also provide world-leading limits on feebly interacting bosons in the mass range of 5 - 25 MeV.
