Standard arguments indicate that first order phase transitions are robust against explicit breaking: when introducing a bare quark mass, then, we expect a first order phase transition which will eventually end in a genuine singularity at some critical point (T c, m c). .

A clear difference of the values for K ∗ and K ∗∗ distinguishes a weak first order transition from a second order one. For example, thermodynamic functions follow the same scaling behavior in a magnetic transition as in the seemingly unrelated gas-liquid transition. Through a detailed study pseudo-critical dynamics in first-order transitions of the mean-field approximation, the Gaussian approximation, the perturbation expansion, and the field-theoretic renormalization-group analysis of a φ 3 theory, we show that the pseudo-critical dynamics in first-order transitions instability fixed points of the theory, together with their associated instability exponents, are quite probably relevant to the scaling and universality behavior exhibited by the first-order.
