Abstract
Vector meson mass values are studied at finite chemical potential and temperature in lattice QCD with lattice size of 24 × 122 × 6 using two flavors of staggered quarks. The investigation focuses on the change of the vector meson mass in the critical region close to Tc with two different types of chemical potentials switched on: the isoscalar chemical potential μs and its isovector counterpart μv. It is found that the vector meson mass increases in the QGP phase with both chemical potentials and decreases with μs in the confinement phase.
