QCD phase diagram from finite energy sum rules
(AMER PHYSICAL SOC, 2011)
Comparison between the continuum threshold and the Polyakov loop as deconfinement order parameters
(American Physical Society, 2017-02)
We study the relation between the continuum threshold s0 within finite energy sum rules and the trace of the Polyakov loop Φ in the framework of a nonlocal SU(2) chiral quark model, establishing a contact between both ...
Relation between the continuum threshold and the Polyakov loop with the QCD deconfinement transition
(American Physical Society, 2019-10-31)
Using vector and axial-vector correlators within finite-energy sum rules with inputs from a chiral quark model, coupled to the Polyakov loop, with nonlocal vector interactions, we extend our previous work to confirm the ...

A QCD sum rule study of Theta(+) in nuclear matter
(Elsevier B.V., 2005-01-27)
We consider a [ud](2)(s) over bar current, in the finite-density QCD sum rule approach, to investigate the scalar and vector self-energies of the recently observed pentaquark state Theta(+)(1540), propagating in nuclear ...

Quark deconfinement and gluon condensate in a weak magnetic field from qcd sum rules
(2015)
We study QCD finite energy sum rules (FESR) for the axial-vector current correlator in the presence of a magnetic field, in the weak field limit and at zero temperature. We find that the perturbative QCD and the hadronic ...
