Abstract
The research status of the shear viscosity of nucleonic matter is reviewed. Some methods to calculate the shear viscosity of nucleonic matter are introduced, including mean free path, Green–Kubo, shear strain rate, Chapman–Enskog and relaxation time approximation. Based on these methods, results for infinite and finite nucleonic matter are discussed, which are attempts to investigate the universality of the ratio of shear viscosity over entropy density and transport characteristics like the liquid–gas phase transition in nucleonic matter. In addition, shear viscosity is also briefly discussed for the quantum chrodynamical matter produced in relativistic heavy-ion collisions.
期刊介绍：
Taking the format of four issues per year, the journal Progress in Particle and Nuclear Physics aims to discuss new developments in the field at a level suitable for the general nuclear and particle physicist and, in greater technical depth, to explore the most important advances in these areas. Most of the articles will be in one of the fields of nuclear physics, hadron physics, heavy ion physics, particle physics, as well as astrophysics and cosmology. A particular effort is made to treat topics of an interface type for which both particle and nuclear physics are important. Related topics such as detector physics, accelerator physics or the application of nuclear physics in the medical and archaeological fields will also be treated from time to time.
