“…In other words, the temperature of thermodynamic system decreases by dividing the Lorentz factor (  ) in relativistic situation. This observation confirms our previous work [20], which shows that the Planck-Einstein relation [21][22][23][24] is right. A moving system which has no energy current exchange with external surroundings becomes cool.…”

The mutual derivation between arbitrary distribution forms of momenta and momentum components of particles produced in an isotropic emission source are systematically studied in terms of probability theory and mathematical statistics. The distributions of rapidities and pseudorapidities are expediently studied. As an example, the classical and relativistic ideal gas models are used to show these distributions by the analytic and Monte Carlo methods. As an application, the experimental rapidity and transverse momentum spectra of light flavor particles produced in high energy collisions are analyzed by a multi-component relativistic ideal gas model in which the single model can be replaced by other models and distributions.

“…In addition, there are other relations such as [25] had not made a conclusion on the relative size of f T and 0 T . We insist on the Planck-Einstein relation to be correct due to invariant T p spectra in high energy collisions [20]. We would like to point out that the temperature discussed above is the so-called effective temperature.…”

“…In the case of the simulations, Cubero et al . 34 Liu 35 proposed a Jüttner velocity distribution 38 as the correct one for a relativistic gas, but each one of them found different temperature transformations, supporting Landsberg 34 and Planck-Einstein 35 results. On the other hand, Requardt 36 and later Przanowski 37 considered covariant formulations of relativistic thermodynamics, and found that the most likely temperature transformation is the one proposed by Ott.…”

“…In recent years, and with the controversy over relativistic transformations for a thermodynamical system still open after more than a century, new tools and computational capabilities have led a to a series of more complex numerical experiments and solutions. For example, the use of molecular dynamics simulations to obtain a statistical definition of temperature 34 , 35 and expansions on covariant formalism for relativistic thermodynamics 36 , 37 have been proposed. In the case of the simulations, Cubero et al .…”

The construction of a relativistic thermodynamics theory is still controversial after more than 110 years. To the date there is no agreement on which set of relativistic transformations of thermodynamic quantities is the correct one, or if the problem even has a solution. Starting from Planck and Einstein, several authors have proposed their own reasoning, concluding that a moving body could appear cooler, hotter or at the same temperature as measured by a local observer. In this article we present a review of the main theories of relativistic thermodynamics, with an special emphasis on the physical assumptions adopted by each one. We also present a set of relativistic transformations that we have derived by assuming the laws of Thermodynamics to be covariant. We found that under such assumptions a moving body appears to be hotter. Since relativistic thermodynamics is a topic that can be treated as part of an undergraduate course of classical thermodynamics or modern physics, the review and our own derivations presented here aim to encourage undergraduate physics students to open a discussion on the fundamental assumptions in thermodynamics and to engage in research activities early in their scientific career.
