Quarkonium Correlators and Heavy Quark Kinetics

Explore the contribution of quarkonium correlators to the properties of heavy quarks in a medium, using lattice QCD calculations. Investigate quarkonium spectral functions, interactions, temperature dependence, and the zero-mode contribution. Make comparisons with potential models and previous findings.

Presentation Transcript

  1. Zero mode contribution to quarkonium correlators and heavy quark kinetics Péter Petreczky Physics Department and RIKEN-BNL in collaboration with S. Datta (TIFR) and A. Jakovác (Budapest) • Quarkonium correlators carry information not only about bound states • but also about the properties of the heavy quark in the medium : • quantify the corresponding contribution in lattice QCD • learn about in-medium properties of heavy quarks

  2. Quarkonium spectral functions interactions : P.P., Teaney, PRD 73 (2006) 014508 calculate the area under the peak using lattice QCD ! E.g. free theory : + quark number susceptibility

  3. Quarkonium correlators in Euclidean time
