FIG. 3: The MC lattice results and the dotted horizontal line are the same as in Fig. 1. The solid lines correspond to the A -BM EoS (9) with σ = 4 . 73, A = 3 . 94 T 3 c , and B = − 2 . 37 T 4 c for ε/T 4 (upper line) and 3 p/T 4 (lower line). as shown in Fig. 3. The parameter σ in Eq. (9) regulates the high temperature behavior of ε/T 4 ∼ = 3 p/T 4 ∼ = σ . As A > 0, the linear in T term gives a negative contribution to p ( T ) and guarantees both the correct high temperature asymptotic behavior of p ( T ) and its strong drop at T near T$_{c}$ . The bag parameter B in Eq. (9) is found to be negative , in contrast to the positive bag constant B in the standard BM EoS (1). Thus, according to the A -BM (9), ε/T 4 approaches its high temperature limit σ from below. This is in agreement with the MC lattice results. An important characteristic of the EoS is the so-called interaction measure, ( ε − 3 p ) /T $^{4}$, which shows the deviation from the system of noninteracting massless particles. For the A -BM EoS (9) the interaction measure reads, The MC lattice results [2] demonstrate a prominent maximum of the function ( ε − 3 p ) /T 4 at T$_{max}$ ∼ = 1 . 1 T$_{c}$ . The maximum of ( ε − 3 p ) /T 4 is described in the A -BM (9). This happens due to different signs of the A- and B-terms ( A > 0, B < 0) in the r.h.s. of Eq. (10). Note that such a maximum is not reproduced by the so-called fuzzy bag model [6]. In that model, there 6 ε − 3 p T 4 = 3 A T 3 + 4 B T 4 .
