Why it is here

A roughly 300 MeV pseudoscalar mediator makes a cosmic-ray-boosted explanation viable beyond the contact limit.

Machine-assisted summary

The authors calculate cosmic-ray production, propagation, and xenon scattering with relativistic kinematics, finding that a spin-dependent pseudoscalar interaction can populate the event window without filling the lower-energy sideband.
