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…
Phenomenological aspects of the exotic quark in 331 models
J. M. Cabarcas, D. Gomez Dumm, R. Martinez
In the context of 331 models we analyze the phenomenology of exotic quarks with electric charge 2/3. We establish bounds for the corresponding masses and mixing angles and stud…
Color neutrality effects in the phase diagram of the PNJL model
D. Gomez Dumm, D. B. Blaschke, A. G. Grunfeld +1
The phase diagram of a two-flavor Polyakov loop Nambu-Jona-Lasinio model is analyzed imposing the constraint of color charge neutrality. Main effects of this constraint are a shrin…
Diquark-antidiquark states with hidden or open charm
Luciano Maiani, Fulvio Piccinini, Antonio D. Polosa +1
Some features and predictions of a recently proposed model based on diquark-antidiquark bound states are illustrated. Its ability in accomodating newly discovered charmed resonance…
Constraints on B and Higgs Physics in Minimal Low Energy Supersymmetric Models
M. Carena, A. Menon, R. Noriega-Papaqui +2
We study the implications of minimal flavor violating low energy supersymmetry scenarios for the search of new physics in the B and Higgs sectors at the Tevatron collider and the L…
tau -> (3 pions) nu_tau : Theory versus Experiment
D. Gomez Dumm, A. Pich, J. Portoles
We analyse tau -> (3 pions) nu_tau decays within the framework of the resonance chiral theory of QCD. We have worked out the relevant Lagrangian that describes the axial-vector cur…
