Boost modes for a massive fermion field
boost symmetry fermion field Wightman function zero mode
2011/9/29
Abstract: We have shown that Wightman function of a free quantum field generates any complete set of solutions of relativistic wave equations. Using this approach we have constructed the complete set ...
Four-dimensional Yang-Mills theory with a three-dimensional fermion membrane
Four-dimensional Yang-Mills theory three-dimensional fermion membrane
2010/12/27
We study the four-dimensional Yang-Mills theory in the presence of a three-dimensional membrane of fermions by lattice Monte Carlo simulations. We analyze the phase structure of this theory at finite...

Domain Wall Fermion Lattice Simulation Quaternion Basis
2011/1/7
In the QCD analysis, when quarks are expressed in quaternion basis, the quark and its charge conjugate together are expressed by octonions and the octonion posesses the triality symmetry. Gluos are ex...
Perturbative renormalization factors and O(a^2) corrections for lattice 4-fermion operators with improved fermion/gluon actions
Perturbative renormalization factors O(a^2) corrections
2011/1/7
In this work we calculate the corrections to the amputated Green's functions of 4-fermion operators, in 1-loop Lattice Perturbation theory. One of the novel aspects of our calculations is that they ar...
Fermion localization on degenerate and critical branes
Fermion localization degenerate critical branes
2010/12/23
In this work we analyze the localization of fermions on degenerate and critical Bloch branes. This is done directly on the original extra-dimensional spatial variable $r$, in constrast to some works t...

Dilaton stabilization by massive fermion matter
Dilaton stabilization massive fermion matter
2010/12/24
The implications for the Dilaton stabilization problem are investigated when the effective potential for this field is generated by the existence of a massive fermion. The previously evaluated two lo...
Fermion localization on branes with generalized dynamics
Fermion localization branes generalized dynamics
2010/12/21
In a recent paper published in this journal, Bazeia and collaborators [Phys. Lett. B 671, (2009)402] analyze braneworld models with nonstandard dynamics. It was found that the generalized braneworld s...
