J.E. Horvath (IAG-Usp, Brazil)

TL;DR
This paper proposes a method to search for primordial quark nuggets, hypothesized superdense remnants from the early universe, among near-Earth asteroids using specific observational signatures.
Contribution
It introduces a novel observational approach to identify primordial quark nuggets among NEAs based on their unique flux and spectral characteristics.
Findings
Potential identification of quark nuggets through high flux ratios and constant lightcurves.
Feasibility of integrating quark nugget searches into existing asteroid observation programs.
Theoretical support for the survival of quark nuggets over cosmological timescales.
Abstract
Primordial Quark Nuggets,remnants of the quark-hadron phase transition, may be hiding most of the baryon number in superdense chunks have been discussed for years always from the theoretical point of view. While they seemed originally fragile at intermediate cosmological temperatures, it became increasingly clear that they may survive due to a variety of effects affecting their evaporation (surface and volume) rates. A search of these objects have never been attempted to elucidate their existence. We discuss in this note how to search directly for cosmological fossil nuggets among the small asteroids approaching the Earth. ``Asteroids'' with a high visible-to-infrared flux ratio, constant lightcurves and devoid of spectral features are signals of an actual possible nugget nature. A viable search of very definite primordial quark nugget features can be conducted as a spinoff of the…
