Abstract
We first extend our formulation for the calculation of - and -meson screening masses to the case of finite chemical potential . We then consider the approach, which is an extrapolation method from an imaginary chemical potential () to a real one (). The feasibility of the method is discussed based on the entanglement Polyakov-loop extended Nambu–Jona-Lasinio (EPNJL) model in 2-flavor system. As an example, we investigate how reliable the approach is for - and -meson screening masses, comparing “screening masses at in the method” with “those calculated directly at .” We finally propose a new extrapolation method and confirm its efficiency.
