Discrete symmetries, invisible axion, and lepton number symmetry in an economic 3-3-1 model
(American Physical Soc, 2014)
On chiral symmetry breaking in a constant magnetic field in higher dimension
(2000-10-19)
Chiral symmetry breaking in the Nambu-Jona-Lasinio model in a constant magnetic field is studied in spacetimes of dimension D > 4. It is shown that a constant magnetic field can be characterized by [D-1/2] parameters. For ...
Probing SU(2) symmetry breaking in the nucleon sea
(1997-05-29)
Investigation of invariant cross-sections for production of K*- and K*0, in the fragmentation region of the proton, in p - p and γ - p reactions, gives a direct and unambiguous probe to the symmetry breaking of the nucleon ...
Perturbative breaking of the pseudospin symmetry in the relativistic harmonic oscillator

Gravitation and duality symmetry
(World Scientific Publ Co Pte Ltd, 2005-09-01)
By generalizing the Hodge dual operator to the case of soldered bundles, and working in the context of the teleparallel equivalent of general relativity, an analysis of the duality symmetry in gravitation is performed. ...

QCD chiral symmetry restoration with a large number of quarks in a model with a confining propagator and dynamically massive gluons
(Elsevier B.V., 2015-05-11)
Considering a QCD chiral symmetry breaking model where the gap equation contains an effective confining propagator and a dressed gluon propagator with a dynamically generated mass, we verify that the chiral symmetry is ...
Inequality between size and charge in spherical symmetry
(American Physical Society, 2016-02-15)
We prove that, for a charged spherically symmetric body, twice the radius is always strictly greater than the charge of the body. We also prove that this inequality is sharp. Finally, we discuss the physical implications ...
Spin and pseudospin symmetries of the Dirac equation with confining central potentials
(2013-03-04)
We derive the node structure of the radial functions which are solutions of the Dirac equation with scalar S and vector V confining central potentials, in the conditions of exact spin or pseudospin symmetry, i.e., when one ...
