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
