Perturbative Quantum Chromodynamics (pQCD)
===========================================

The **pQCD module** computes the equation of state (EoS) for Quantum Chromodynamics (QCD) matter at **high densities and zero temperature** at next-to-leading-order.

A few comments on the physics background of the pQCD EoS module:

- The pQCD EoS is valid at high densities. It is not expected to be accurate at low densities, and can produce negative baryon density at low chemical potentials. 
- The module will filter out any rows in the output that contain NaN values, but it is the user's responsibility to ensure that the input parameters are chosen such that the output is physically meaningful.
