2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/195981We present the Taylor expansion coefficients of the pressure in quark number chemical potential $μ_0=μ_B / 3=μ_u=μ_d$, for the strongly interacting matter as described by the PNJL model for two light degenerate flavours of quarks u and d. The expansion has been done upto eighth order in $μ_0$, and the results are consistent with recent estimates from Lattice. We have further obtained the specific heat $C_V$, squared speed of sound $v_s^2$ and the conformal measure $\cC$.13 pages, 8 figures, References added, some discussions on Fig. 4 modified, one table added, results unchanged, version to appear in Phys.
