Abstract
We study the spectral densities of (pseudo)scalar currents at finite temperature in general case when mass of two quarks are different. Such spectral densities are necessary for the phenomenological investigation of hadronic parameters. We use quark propagator at finite temperature and show that an additional branch cut arises in spectral density, which corresponds to particle absorption from the medium. The obtained results at T \rightarrow 0 limit are in good agreement with the vacuum results.
