QED vacuum fluctuations and induced electric dipole moment of the neutron
C. A. Dominguez, H. Falomir, M. Ipinza +3
Quantum fluctuations in the QED vacuum generate non-linear effects, such as peculiar induced electromagnetic fields. In particular, we show here that an electrically neutral partic…
Charmonium in the vector channel at finite temperature from QCD sum rules
C. A. Dominguez, M. Loewe, J. C. Rojas +1
Thermal Hilbert moment QCD sum rules are used to obtain the temperature dependence of the hadronic parameters of charmonium in the vector channel, i.e. the / resonance mass…
Electromagnetic and Scalar Pion form factor in the Kroll-Lee-Zumino model
C. A. Dominguez, J. I. Jottar, M. Loewe +1
The renormalizable Abelian quantum field theory model of Kroll, Lee, and Zumino is used at the one loop level to compute vertex corrections to the tree-level, Vector Meson Dominanc…
Confronting QCD with the experimental hadronic spectral functions from tau-decay
C. A. Dominguez, N. F. Nasrallah, K. Schilcher
The (non-strange) vector and axial-vector spectral functions extracted from -decay by the ALEPH collaboration are confronted with QCD in the framework of a Finite Energy QCD sum…
