- Measuring shear viscosity using correlations (2007)
- Measurements of transverse momentum fluctuations can be used to determine the shear viscosity . We use current data to estimate the viscosity-to-entropy ratio in the range from 0.08 to 0.3, and discuss how future measurements can reduce this uncertainty.
- Status and promise of particle interferometry in heavy-ion collisions (2007)
- After five years of running at RHIC, and on the eve of the LHC heavy-ion program, we highlight the status of femtoscopic measurements. We emphasize the role interferometry plays in addressing fundamental questions about the state of matter created in such collisions, and present an enumerated list of measurements, analyses and calculations that are needed to advance the field in the coming years.
