Abstract
The linear- model has been widely used to describe the chiral phase transition. Numerically, the critical temperature of the chiral phase transition is in agreement with other effective theories of QCD. However, in the large- limit scales as which is not in line with the NJL model and with basic expectations of QCD, according to which is --just as the deconfinement phase transition- -independent. This mismatch can be corrected by a phenomenologically motivated temperature dependent parameter.
