High-Density behavior of symmetry energy and speed of sound in the dense matter within an effective chiral model

Prashant Thakur, N. K. Patra, T. K. Jha +1

With an effective chiral model, we investigate how the mesonic cross couplings $\sigma -\rho$ and $\omega -\rho$ affect the density content of the symmetry energy and its higher-order slope paramete…
