Feasibility of Low-Energy True Muonium Photoproduction

Benjamin Banto Oberhauser, Ivo Schulthess, Paolo Crivelli

Proposed gamma sources could supply the energies and rates needed to produce true muonium near threshold with backgrounds kept below signal level.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We show that the proposed Gamma Factory at CERN could provide the necessary photon energies and rates for the production of true muonium. Furthermore, cut-based selections are shown to suppress the background below the expected signal level.

C2weakest assumption

The Monte Carlo simulations of signal and dominant background processes accurately represent the real physics, and the Gamma Factory will deliver the projected photon fluxes and energies.

C3one line summary

Feasibility study shows low-energy photoproduction of true muonium is possible at the Gamma Factory with background suppression via cut-based selections.
