Report

Inclusive and effective bulk viscosities in the hadron gas

Autor: Rose, J. -B., Torres-Rincon, J. M., Elfner, H.

Publikováno v: J. Phys. G: Nucl. Part. Phys. 48 (2021) 015005

We estimate the temperature dependence of the bulk viscosity in a relativistic hadron gas. Employing the Green-Kubo formalism in the SMASH (Simulating Many Accelerated Strongly-interacting Hadrons) transport approach, we study different hadronic syst

Report

Shear viscosity of a hadron gas and influence of resonance lifetimes on relaxation time

Autor: Rose, J. -B., Torres-Rincon, J. M., Schäfer, A., Oliinychenko, D. R., Petersen, H.

Publikováno v: Phys. Rev. C 97, 055204 (2018)

We address a discrepancy between different computations of $\eta/s$ (shear viscosity over entropy density) of hadronic matter. Substantial deviations of this coefficient are found between transport approaches mainly based on resonance propagation wit

Report

Systematic errors in transport calculations of shear viscosity using the Green-Kubo formalism

Autor: Rose, J. -B., Torres-Rincon, J. M., Oliinychenko, D., Schäfer, A., Petersen, H.

The purpose of this study is to provide a reproducible framework in the use of the Green-Kubo formalism to extract transport coefficients. More specifically, in the case of shear viscosity, we investigate the limitations and technical details of fitt

Report

Equilibration and freeze-out of an expanding gas in a transport approach in a Friedmann-Robertson-Walker metric

Autor: Tindall, J., Torres-Rincon, J. M., Rose, J. B., Petersen, H.

Publikováno v: Phys.Lett. B770 (2017) 532-538

Motivated by a recent finding of an exact solution of the relativistic Boltzmann equation in a Friedmann-Robertson-Walker spacetime, we implement this metric into the newly developed transport approach Simulating Many Accelerated Strongly-interacting

Report

Extracting the bulk viscosity of the quark-gluon plasma

Autor: Rose, J. -B., Paquet, J. -F., Denicol, G. S., Luzum, M., Schenke, B., Jeon, S., Gale, C.

We investigate the implications of a nonzero bulk viscosity coefficient on the azimuthal momentum anisotropy of ultracentral relativistic heavy ion collisions at the Large Hadron Collider. We find that, with IP-Glasma initial conditions, a finite bul
