Dilaton stabilization by massive fermion matter
Alejandro Cabo, Matts Roos, Encieh Erfani
The study started in a former work about the Dilaton mean field stabilization thanks to the effective potential generated by the existence of massive fermions, is here extended. Th…
Could Fermion Masses Play a Role in the Stabilization of the Dilaton in Cosmology?
Alejandro Cabo, Robert Brandenberger
We study the possibility that the Dilaton is stabilized by the contribution of fermion masses to its effective potential. We consider the Dilaton gravity action in four dimensions…
Remark on charge conjugation in the non relativistic limit
A. Cabo, D. B. Cervantes, H. Perez Rojas +1
We study the non relativistic limit of the charge conjugation operation in the context of the Dirac equation coupled to an electromagnetic field. The limit is well defined…
Modified initial state for perturbative QCD
Marcos Rigol, Alejandro Cabo
A particular initial state for the construction of the perturbative expansion of QCD is investigated. It is formed as a coherent superposition of zero momentum gluon pairs and show…
Can the Red Shift be a consequence of the Dilaton field?
Alejandro Cabo, Alexis Amezaga
The possibility that the expansion rate of the Universe, as reflected by the Red Shift, could be produced by the existence of the dilaton field is explored. The analysis starts fro…
