Y. Koma -- Heavy Quark Potentials in Lattice QCD

V. Dmitrasinovic --- DsJ*(2317), and DJ*(2308) as candidates for tetraquarks?

I asked the question: "What one thing would you like astrophysicists to talk away from your talk?"

Answer: The answer to this question is not clear at this point, but it may require 5-10 years to determine if the present work has implications for astrophysics.

In discussion, it was stated: We have seen three quark baryons (protons, neutrons) and q-qbar mesons, but multi-quark states are not observed and not well understood, and they may well exist. It therefore seems not unlikely that multiquark states are going to important at nuclear and super-nuclear density. Thus, to understand supernuclear density matter, we are going to need much work on multi-quark states.

There are some major uncertainties in this work. These include color confinement violation, which (with three colors) is expected; in tetraquarks, there are two color singlets; in pentaquarks, more, etc.... All color singlets may mix. Therefore al color eigenstates ought to be observable.
