Nonperturbative aspects of the two-dimensional massive gauged Thirring model
(World Scientific Publ Co Pte Ltd, 2014-09-20)
In this paper, we present a study based on the use of functional techniques on the issue of insertions of massive fermionic fields in the two-dimensional massless gauged Thirring model. As it will be shown, the fermionic ...

Generalized variational procedure: an application to nonperturbative QCD
(World Scientific, 2013-07)
We present a generalized variational procedure oriented to the algebraic solution of many-body Hamiltonians expressed in bosonic and fermionic variables. The method specializes in the nonperturbative regime of the solutions. ...
STRONG COUPLING LIMITS and QUANTUM ISOMORPHISMS of THE GAUGED THIRRING MODEL
(World Scientific Publ Co Pte Ltd, 2011-04-10)
We have studied the quantum equivalence in the respective strong coupling limits of the bidimensional gauged Thirring model with both Schwinger and Thirring models. It is achieved following a nonperturbative quantization ...
New exotic charmonium states
(CHINESE PHYSICAL SOC, 2010)
In the last years many states in the charmonium mass region were discovery by BABAR, Belle and CDF collaborations I discuss some of these discoveries, and how the QCD Sum Rule approach can be used to understand the structure ...
The charmed pentaquark Θc(3250) from QCD sum rules.
(World Scientific Publishing Company, 2014-01-22)
We study, using the QCD sum rule framework, the possible existence of a charmed
pentaquark that we call Θc(3250). In the QCD side we work at leading order in αs and
consider condensates up to dimension 10. The mass ...
