[en] The gluon polarization tensor for quark–gluon plasma with shear viscosity is derived with the viscous chromohydrodynamics. The longitudinal and transverse dielectric functions are evaluated from the gluon polarization tensor, through which the polarization energy loss suffered by a fast quark traveling through the viscous quark–gluon plasma is investigated. The numerical analysis indicates that shear viscosity significantly reduces the polarization energy loss. (paper)
