Physics potential of a low-energy FCC-hh

We present an early assessment of the physics reach of a pp collider at $\sqrt{S}=37.5$~TeV, with 15\,\iab of integrated luminosity. We select a few topics, focusing on the key 100~TeV deliverables documented in the FCC CDR, namely the searches at high mass, the search for WIMP dark matter candidates, the signatures for a strong first order EW phase transition, and the Higgs precision measurements.
