Summary: Using the momentum space representation, we determine the energy eigenvalues, eigenfunctions and the high-temperature thermodynamic properties of the Dirac oscillator in one dimension in the presence of a minimal length given by \((\Delta X)_{\min}=\hbar \sqrt{\beta}\), where \(\beta\) is the deformation parameter of the modified commutation relation \([X, P] = i\hbar (1 + \beta P^{2})\). The obtained results suggest that the effect of the minimal length could be detected in ultrarelativistic heavy-ion collisions.
