We study the scaling properties of QCD in temperature and mass
close to the thermal crossover, and for quark masses ranging from the heavy quark regime to the physical values. The lattice results are obtained in the fixed scale approach, either with anisotropic simulations with Nf=2+1 flavours,
and with simulations of Nf = 2 +1 + 1 flavours at maximal twist. We note that a simple...
Chiral phase transition has been a topic of interest over decades
and order of the chiral phase transition has an effect on the global
phase diagram of QCD. In this talk I will review some of our recent
calculations towards the limit of 2 massless flavors. I shall
start with the determination of the chiral transition temperature
and then show how our calculation is able to throw some light...
We summarise recent theoretical results on the QCD phase diagram and the properties
of QCD's critical point based on a combination of lattice QCD and Dyson-Schwinger
equations.
Using lattice input for the quenched gluon propagator, our approach correctly reproduced
and predicted Nf=2+1 flavour lattice results for the quark condensate and the unquenched
electric and magnetic gluon...
I will review recent advances on the QCD phase diagram, regarding mostly the nature of the chiral phase transition and its interplay with $U(1)_A$ restoration. Ward Identities and Effective Theories will be the main theoretical tools. The former allow to establish the thermal behaviour of chiral and $U(1)_A$ partners whereas the latter turns out to be quite fruitful for certain observables...
In this talk I will present our very recent work based on [1].
We introduce novel relations between the derivatives ($\partial^{n}{\rho(\lambda,m_l)}/{\partial m_l^{n}}$) of the
Dirac eigenvalue spectrum ($\rho(\lambda,m_l)$) with respect to the light sea quark mass ($m_l$)
and the $(n+1)$-point correlations among the eigenvalues ($\lambda$) of the massless
Dirac operator. Using these...
