EUSO-SPB2 sensitivity to macroscopic dark matter

Abstract

Macroscopic dark matter (or macro) provides a broad class of alternative candidates to particle dark matter. These candidates would transfer energy primarily through elastic scattering, and this linear energy deposition would produce observable signals if a macro were to traverse the atmosphere. We study the fluorescence emission produced by a macro passing through the atmosphere. We estimate the sensitivity of EUSO-SPB2 to constrain the two-dimensional parameter space ($\ddot{I}ƒ$ vs. $M$), where $M$ is the macro mass and $\ddot{I}ƒ$ its cross sectional area.
