A New Source of Millicharged Particles: Secondary Showers in the LHC Forward Absorber

Azam Zabihi, Jyotismita Adhikary, Peiran Li, Sebastian Trojanowski, Zhen Liu

Secondary production in the LHC TAXN absorber generates a substantial millicharged particle flux that boosts forward detector signals by about 50 percent for light masses.

Claims

C1strongest claim

By combining Monte Carlo simulations with Geant4-based modeling, we show that these secondary cascades yield a substantial mCP flux that complements the primary production from the interaction point. For the proposed FORMOSA detector, this contribution can enhance the expected signal yield by approximately 50% for m_χ ≲ 0.1 GeV.

C2weakest assumption

The Monte Carlo and Geant4 modeling accurately captures the production rate of millicharged particles inside the hadronic and electromagnetic showers initiated by neutral particles striking the TAXN absorber.

C3one line summary

Secondary cascades in the TAXN absorber produce a substantial millicharged particle flux that complements primary production and boosts FORMOSA signals by ~50% for m_χ below 0.1 GeV.
