Participant matter can serve as an indicator of thermalization.

Degree of thermalization is similar across different nuclei at this energy.

Abstract

We aim to study the participant-spectator matter over a wide range of energies of vanishing flow and masses. For this, we employed different model parameters at central and semi-central colliding geometries. Remarkably, a nearly mass independent nature of the participant matter was obtained at the energy of vanishing flow. This makes it a very strong alternative candidate to study the energy of vanishing flow. We also show that the participant matter can also act as an indicator to study the degree of thermalization. The degree of thermalization reached in central collisions is nearly the same for different colliding nuclei at the energy of vanishing flow.
