Sample Text	The status of the hidden beauty state Y-b is not clear up to now. The deviations from the expected behavior can provide a clue to consider it as an exotic meson candidate. Assuming the Y-b resonance as a tetraquark, we estimated its mass and pole residue, both at vacuum and T not equal 0 temperatures by calculating hot-medium contributions to hadronic parameters in the framework of Thermal QCD sum rules. Our results depict that the mass and pole residue values decrease dramatically at the vicinity of a critical temperature. Comparison of our results with the recent experimental data and theoretical results might be helpful in understanding the internal structure of bottomonium-like Y-b state.
