Magnetic Catalysis of charmonium in the vector channel
Cesareo A. Dominguez, Michael Koning, Luis A. Hernández
We investigate the impact of an external magnetic field on the vector charmonium system within the framework of Hilbert moment QCD sum rules. By incorporating magnetic corrections…
Magnetic and density effects on the nucleon axial coupling
C. A. Dominguez, M. Loewe, C. Villavicencio +1
Using appropriate QCD finite energy sum rules, we discuss the influence of an external magnetic field and baryonic density on the axial-vector coupling constant . This scena…
QCD determination of the magnetic field dependence of QCD and hadronic parameters
C. A. Dominguez, M. Loewe, Cristian Villavicencio
A set of four Finite Energy QCD sum rules are used to determine the magnetic field dependence of the sum of the up- and down-quark masses of QCD, , the pion decay cons…
Thermo-magnetic evolution of the QCD strong coupling
Alejandro Ayala, C. A. Dominguez, Saul Hernandez-Ortiz +4
We study the one-loop gluon polarization tensor at zero and finite temperature in the presence of a magnetic field, to extract the thermo-magnetic evolution of the strong coupling…
Finite Temperature QCD Sum Rules: a Review
Alejandro Ayala, C. A. Dominguez, M. Loewe
The method of QCD sum rules at finite temperature is reviewed, with emphasis on recent results. These include predictions for the survival of charmonium and bottonium states, at an…
Thermo-magnetic properties of the strong coupling in the local Nambu--Jona-Lasinio model
Alejandro Ayala, C. A. Dominguez, L. A. Hernandez +4
We study the thermo-magnetic properties of the strong coupling constant G and quark mass M entering the Nambu-Jona-Lasinio model. For this purpose, we compute the quark condensate…
Inverse magnetic catalysis from the properties of the QCD coupling in a magnetic field
Alejandro Ayala, C. A. Dominguez, L. A. Hernandez +2
We compute the vacuum one-loop quark-gluon vertex correction at zero temperature in the presence of a magnetic field. From the vertex function we extract the effective quark-gluon…
The magnetized effective QCD phase diagram
Alejandro Ayala, C. A. Dominguez, L. A. Hernandez +2
The QCD phase diagram in the temperature versus quark chemical potential plane is studied in the presence of a magnetic field, using the linear sigma model coupled to quarks. It is…
The (magnetized) effective QCD phase diagram
Alejandro Ayala
I present the highlights of a recent study of the effective QCD phase diagram on the temperature T and quark chemical potential mu plane, where the strong interactions are modeled…
Quark deconfinement and gluon condensate in a weak magnetic field
Alejandro Ayala, C. A. Dominguez, L. A. Hernandez +3
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 th…
Weinberg sum rules at finite temperature
A. Ayala, C. A. Dominguez, M. Loewe +1
The saturation of the two Weinberg sum rules is studied at finite temperature, using recent independent QCD sum rule results for the thermal behaviour of hadronic parameters in the…
Dimuon production from in-medium rho decays from QCD sum rules
Alejandro Ayala, C. A. Dominguez, Luis Alberto Hernandez +2
We compute the dimuon-excess invariant mass distribution at the rho-meson peak in the context of relativistic heavy-ion collisions at SPS energies. The temperature, T, and chemical…
