In-Medium Quarkonia at SPS, RHIC and LHC
Xingbo Zhao, Andrew Emerick, Ralf Rapp
A kinetic-rate equation approach in a thermally expanding medium is employed to calculate the evolution of charmonium and bottomonium distributions in heavy-ion collisions. The equ…
Update on Chiral Symmetry Restoration in the Context of Dilepton Data
Ralf Rapp
We evaluate currently available information on low-mass dilepton and direct-photon emission spectra measured in ultrarelativistic heavy-ion collisions. In the first part an attempt…
Quantitative sum rule analysis of low-temperature spectral functions
Nathan P. M. Holt, Paul M. Hohler, Ralf Rapp
We analyze QCD and Weinberg-type sum rules in a low-temperature pion gas using vector and axial-vector spectral functions following from the model-independent chiral-mixing scheme.…
Evaluating chiral symmetry restoration through the use of sum rules
Paul M. Hohler, Ralf Rapp
We pursue the idea of assessing chiral restoration via in-medium modifications of hadronic spectral functions of chiral partners. The usefulness of sum rules in this endeavor is il…
Non-perturbative Heavy-Flavor Transport at RHIC and LHC
Min He, Rainer J. Fries, Ralf Rapp
We calculate open heavy-flavor (HF) transport in relativistic heavy-ion collisions by applying a strong-coupling treatment in both macro- and microscopic dynamics (hydrodynamics an…
A T-Matrix Calculation for in-Medium Heavy-Quark Gluon Scattering
Kyle Huggins, Ralf Rapp
The interactions of charm and bottom quarks in a Quark-Gluon Plasma (QGP) are evaluated using a thermodynamic 2-body T-matrix. We specifically focus on heavy-quark (HQ) interaction…
-Meson as Quantitative Probe of Diffusion and Hadronization in Nuclear Collisions
Min He, Rainer J. Fries, Ralf Rapp
The modifications of -meson spectra in ultrarelativistic heavy-ion collisions are identified as a quantitative probe of key properties of the hot nuclear medium. This is enabl…
Sum rule analysis of vector and axial-vector spectral functions with excited states in vacuum
Paul M. Hohler, Ralf Rapp
We simultaneously analyze vector and axial-vector spectral functions in vacuum using hadronic models constrained by experimental data and the requirement that Weinberg-type sum rul…
