摘要：

We propose a model for baryons at a finite temperature using AdS/QCD correspondence. In this model, we modify the AdS spacetime into the AdS-Schwarzchild spacetime and consider a couple of bulk spinors in this background. Solving this model, we get an eigenvalue equation for the baryon masses. We then investigate the effects of temperature on the baryon masses numerically and find an interesting temperature dependence. Our result is consistent with the results from lattice QCD and other phenomenological models.
