Description

By identifying {\em massive} renormalization group (RG) properties within the hard thermal loop (HTL)
formalism, we resum to all orders $\alpha_S^p, p\ge 3$ the leading and next-to-leading logarithmic
soft mode $m_E\sim \alpha_S^{1/2} \mu_B$ contributions to the cold and dense QCD pressure
at high baryon chemical potential $\mu_B$.
We obtain noticeably reduced residual scale dependence with respect to the state-of-the art results.
We will discuss applications to the NNLO Equation of State of cold and dense
quark matter, also including extension to massive quarks, relevant in particular for the phenomenology of neutron stars.

Mostly based on L. Fernandez and J.-L. Kneur, arXiv:2109.02410 and more recent work in progress.
