Hypothesis
How do collective effects influence the sensitivity of silicon detectors to relativistic particles?
Conclusion
The inclusion of collective effects enhances the sensitivity of silicon detectors to relativistic particles.
Supporting Evidence
- Small detectors with low energy thresholds can outperform larger detectors for certain particle searches.
- Collective effects shift the recoil ionization spectrum towards higher energies.
- The study benchmarks existing tools against electron energy-loss spectroscopy data.
Takeaway
This study shows that small detectors can be better at finding certain particles than larger ones if they can detect very low energy signals.
Methodology
The authors calculated the low-energy excitation cross section for relativistic feebly interacting particles scattering from silicon detectors.
Limitations
The study focuses on silicon and may not generalize to all materials.
