Constraining Tsallis Corrections to Photon Reheating from Electron-Positron Annihilation: A Phenomenological Approach
Matias P. Gonzalez
In this work we generalize the entropy transfer from electron-positron annihilation to photons in the early Universe. The generalization is implemented within the Tsallis formalism…

Bounds on the Tsallis Parameter from a deformed Neutrino Sector in the Early Universe
Matias P. Gonzalez
We generalize neutrino energy density content in the early universe near BBN era MeV within Tsallis nonextensive statistics. By using Curado-Tsallis constraints we obtai…

WIMP Freeze-out dynamics under Tsallis statistics
Matias P. Gonzalez, Roberto A. Lineros
We generalize thermal WIMP (Weakly Interacting Massive Particle) freeze-out within Tsallis nonextensive statistics. Using Curado-Tsallis -distributions we compute $…
