Event details

​The neutral, scalar state uuddss (S) may be compact and relatively deeply bound, in which case it would be very long-lived or stable.   Lattice QCD cannot yet reliably calculate the mass, so experiment must be our guide to its existence.  I will show that such a particle would have have escaped detection in lab experiments to date and outline experimental strategies to discover it.  If  the S exists it can be a component of or possibly all of the dark matter, and I will outline some of the consequences and constraints.  It can also provide a simultaneous resolution to the muon g-2 anomaly and explanation for why the lattice calculation of the Hadronic Vacuum Polarization disagrees with the experimental determination using the R-ratio method.
