No significant GeV emission from 223 SLSNe constrains GeV-to-optical efficiency to η < 1.3×10^{-3}, with <0.7% of events allowed above 10^{-2}; SN 2017egm shows a ~4σ excess favoring magnetar origin while SN 2018bsz does not.

On the Gamma-ray Efficiency of Superluminous Supernovae: Potential Detections and Population-Level Constraints
No significant GeV emission from 223 SLSNe constrains GeV-to-optical efficiency to η < 1.3×10^{-3}, with <0.7% of events allowed above 10^{-2}; SN 2017egm shows a ~4σ excess favoring magnetar origin while SN 2018bsz does not.
