Electromagnetic proton form factors in dual large- QCD: an update
B. Bisschoff, C. A. Dominguez, L. A. Hernandez
An updated determination is presented of the electric and magnetic form factors of the proton, in the framework of a dual-model realization of QCD in the limit of an infinite numbe…
Tests of quark-hadron duality in tau-decays
C. A. Dominguez, L. A. Hernandez, K. Schilcher +1
An exhaustive number of QCD finite energy sum rules for -decay together with the latest updated ALEPH data is used to test the assumption of global duality. Typical checks are t…
Quark-hadron duality: pinched kernel approch
C. A. Dominguez, L. A. Hernandez, K. Schilcher +1
Hadronic spectral functions measured by the ALEPH collaboration in the vector and axial-vector channels are used to study potential quark-hadron duality violations (DV). This is do…
Determination of the temperature dependence of the up- down-quark mass in QCD
C. A. Dominguez, L. A. Hernandez
The temperature dependence of the sum of the QCD up- and down-quark masses, and the pion decay constant, , are determined from two thermal finite energy QCD sum…
Thermal photon production from gluon fusion induced by magnetic fields in relativistic heavy-ion collisions
Alejandro Ayala, Jorge David Castano-Yepes, C. A. Dominguez +1
We compute the production of thermal photons in relativistic heavy-ion collisions by gluon fusion in the presence of an intense magnetic field, and during the early stages of the r…
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…
Tau-decay hadronic spectral functions: probing quark-hadron duality
C. A. Dominguez, L. A. Hernandez, K. Schilcher +1
The vector and axial-vector ALEPH hadronic spectral functions from -decay are used to probe potential quark-hadron duality violations (DV). This is done in the framework of fini…
