There are no three regimes of QCD, as speculated in that paper. There are only two, separated by already well known $T_csim 155, MeV$. Above it electric interactions are screened rather then confined. Magnetic ones remain confined all the way to $Trightarrow infty$. Spectrum of mesonic screening masses is there, but they do not represent real masses. At high $T$ they correspond to heavy quarkonia of 2+1 d gauge theory, which is well known to be a confining theory. There is no reason to expect any transition unbinding them, at $Tsim 1, GeV$ as claimed. I make calculation of correction to screening masses in 2+1d at high temperature including spatial screening tension and find results in agreement with recent lattice data.
In his recent Comments E. Shuryak reiterates old, unfortunately misleading arguments in favor of deconfined Quark-Gluon Plasma (QGP) immediately above the chiral restoration pseudocritical temperature. In a Comment devoted to our view of QCD at high
While the QCD Lagrangian as the whole is only chirally symmetric, its electric part has larger chiral-spin SU(2)_{CS} and SU(2N_F) symmetries. This allows separation of the electric and magnetic interactions in a given reference frame. Artificial tru
The Heavy quark effective field theory (HQEFT) is revisited in a more intuitive way. It is shown that HQEFT is a consistent large component QCD of heavy quarks. In the non-relativistic limit, HQEFT recovers the non-relativistic QCD (NRQCD). The resul
The graviton solutions for the glueball spectrum of ref. cite{Rinaldi:2017wdn} interpreted in a different manner lead to very interesting results which we describe in this comment.
We discuss various aspects of models with long-lived or stable colored particles. In particular we focus on an ideal Quirk model with electroweak neutral heavy (O(TeV)) particles which carry ordinary color and another $ SU(3)$ color with a very low s
