TL;DR
This paper compares two models for how massive quark nuggets deposit energy in Earth's atmosphere, revealing a large discrepancy and estimating detection sensitivities for space-based and suborbital experiments.
Contribution
It identifies a significant difference between two modeling approaches and evaluates the potential for detecting macroscopic dark matter with current experiments.
Findings
Discrepancy of 14 orders of magnitude in macro luminosity predictions.
Estimated detection sensitivities for Mini-EUSO, POEMMA, and EUSO-SPB2.
Comparison of modeling formalisms for macro energy deposition.
Abstract
We compare two different formalisms for modeling the energy deposition of macroscopically sized/massive quark nuggets (a.k.a. macros) in the Earth's atmosphere. We show that for a reference mass of 1 g, there is a discrepancy in the macro luminosity of about 14 orders of magnitude between the predictions of the two formalisms. Armed with our finding we estimate the sensitivity for macro detection at space-based (Mini-EUSO and POEMMA) and suborbital (EUSO-SPB2) experiments.
