Özet
In the present work, D-s and B-s meson parameters are investigated in the framework of thermal QCD sum rules. The temperature dependences of the mass and the leptonic decay constants are investigated by using Borel transform sum rules and Hilbert moment sum rules. To increase the sensitivity, the vacuum contributions are subtracted from the thermal expressions and the temperature dependences of the leptonic decay constants and meson masses are studied.
