Dark Matter Candidate within the Standard Model

It is possible that there is a so-far-undiscovered deeply-bound state of 6 quarks (uuddss) denoted S for Sexaquark. If it exists, the S can naturally be stable enough and have the correct abundance to be the Dark Matter. I will discuss the key aspects of particle physics, cosmology and astrophysics underlying this claim. In particular 1) Why an S would not yet have been discovered by lattice QCD in the HALQCD searches applicable for a loosely-bound state, and why the Luscher-method searches with > 400 MeV pion masses are not sufficient; 2) Probes of and constraints on S Dark Matter; and 3) How the S could be found by Belle-II.
