Results are presented from a Monte Carlo simulation of the Nambu – Jona-Lasinio model with SU(2)⊗SU(2) chiral symmetry and Nf = 2 flavors of fermion. We show that fits to the equation of state are sensitive to the shape and extent of the assumed scaling region; the best fits favour a triviality scenario predicted by the large-Nf approximation, in which the… (More)
