Summary
Within the non-extensive statistical approach, we generalize the linear sigma model.
In the framework of it the chiral phase transition is investigated at finite temperature and baryon chemical potential.
The corresponding non-extensive parameter, q, indeed affects the critical temperature, T_c, even when the chemical potential does not vanish.
The critical endpoint (CEP), on the other hand, carries higher chemical potential but lower temperature with q increasing due to the non-extensive effects.
