Title:Baryon number conservation and enforced electric charge neutrality for bulk viscosity in quark matter

Authors:Hui Dong, Nan Su, Qun Wang
View PDF
Abstract: General constraints on fluid velocity divergences for particles in quark matter are derived from baryon number conservation and enforced electric charge neutrality. A new oscillation pattern in three-flavor normal quark matter satisfying these conditions is found and its bulk viscosity is calculated. The result may have astrophysical implication for maximum rotation frequencies of compact stars.
