Description

Supernova remnants and compact binary mergers are prime candidates for Galactic cosmic‑ray acceleration. We have evidence that HESS J1731-347 and GW170817 have the capacity to accelerate hadrons to TeV energies and could potentially harbor strange quark matter (SQM), thereby inspiring a quest for strangelets. A transition from the 2SC to CFL phase in quark matter could release strangelets whose annihilation or decay leaves distinct imprints in cosmic rays and VHE gamma rays. Using H.E.S.S., HAWC and Fermi-LAT data and forecasting for CTAO, we model strangelet‑induced spectral features, derive the implied strangelet properties, and quantify CTAO's ability to detect or constrain them.
