Violations of Lorentz Covariance in Light Front Quark Models
K. Bodoor, H. J. Weber, T. Frederico +1
Electromagnetic form factors of the nucleon from relativistic quark models are analyzed: results from null-plane projection of the Feynman triangle diagram are compared with a Baka…
Pairs of charged heavy-leptons from an SU(3) X U(1) model at CERN LHC
J. E. Cieza Montalvo, M. D. Tonasse
One of the versions of the SU(3)$_L\otimesU(1)_N$ electroweak model predicts charged heavy-leptons which do not belong to any class of heavy-leptons proposed up to now. We investig…
Relativistic Quark Spin Coupling Effects in the Correlations Between Nucleon Electroweak Properties
E. F. Suisso, W. R. B. de Araujo, T. Frederico +2
We investigate the effect of different relativistic spin couplings of constituent quarks on nucleon electroweak properties. Within each quark spin coupling scheme the correlations…
A Dirac-Hartree-Bogoliubov approximation for finite nuclei
B. V. Carlson, D. Hirata
We develop a complete Dirac-Hartree-Fock-Bogoliubov approximation to the ground state wave function and energy of finite nuclei. We apply it to spin-zero proton-proton and neutron-…
Uniaxial Lifshitz Point at
Luiz C. de Albuquerque, Marcelo M. Leite
The critical exponents and of a uniaxial Lifshitz point are calculated at two-loop level using renormalization group and -expansion techniques. We…
Rho-Nucleon Tensor Coupling and Charge-Exchange Resonances
C. De Conti, A. P. Galeao, F. Krmpotic
The Gamow-Teller resonances are discussed in the context of a self-consistent RPA, based on the relativistic mean field theory. We inquire on the possibility of substituting the ph…
