نوع پژوهش	مقاله چاپ‌شده در مجلات علمی
کلیدواژه‌ها	Quark-Hadron Phase transition‎, ‎Brane-World
چکیده	‎A DGP brane-world framework is picked out to study quark-hadron phase transition problem‎. ‎The model also includes a bulk scalar field in agreement with string theory prediction‎. ‎The work is performed using two formalisms as‎: ‎smooth crossover approach and first order approach‎, ‎and the results are plotted for both branches of DGP model‎. ‎General behavior of temperature is the same in these two approaches and it decrease with increasing time and expanding Universe‎. ‎Phase transition occurs at about micro-second after the big bang‎. ‎The results show that transition time depends on brane tension value in which larger brane tension comes to earlier transition time‎.
