Abstract: (SISSA)

The first-order confinement transition of a stronglycoupled composite dark matter theory can provide a possible sourceof gravitational waves in the early universe. In this work, onbehalf of the Lattice Strong Dynamics (LSD) Collaboration, wepresent our recent investigation on the finite temperatureconfinement transition of the one-flavor SU(4) dark gauge theory namedHyper Stealth Dark Matter (HSDM). The dark matter candidate in thistheory is a composite bosonic baryon and can have a remarkably lowmass of a few GeV. We expect the finite temperature transitionto be first-order over at leastin some finite range of fermionic massesand to be a potential source of observable gravitationalradiation. The finite temperature simulation of one-flavor SU(4) isdone by using M\"{o}bius Domain wall fermions.The order of the transition and its fermionic massdependence are exploredby monitoring the Polyakov loop, chiralcondensate and topological chargeusing three lattice volumes at

N_t=8
