Some questions to be answered.
- what is color singlet and color octet state of quarkonia?
- how can one obtain these potentials?
- these potentials have been found by debyendu bala but for plasma of gluons only i.e. Pure SU(3) gauge theory. But we have to find it with presence of 2+1 flavour QCD.
- How does quarkonium helps to understand characteristics of Quark gluon plasma? (More than 95% of the produced heavy-quarks at the RHIC and LHC hadronized to heavy-flavor baryons and mesons. A small fraction of them forms Quarkonium states (
) and mesons. Those states are particularly interesting probes because of two heavy quarks in the hadron. Quarkonia with different hadron sizes and binding strengths are probes of the Debye screening lengths in the medium and the medium-induced decays since these finite temperature modifications produce different surviving probabilities inside QGP. Moreover, ab-initio calculations of equilibrium properties on the lattice are available, allowing for a data-model comparison.)
