ANÁLISE GEOMORFOLOGICA PRELIMINAR DO CORRÉGO DO CERRADO NO MUNICÍPIO DE CANÁPOLIS/MG

Historicamente rios e cidades estiveram intrinsecamente ligados, foi através dos rios que impérios se desenvolveram. Entender a dinâmica do relevo e dos rios é importante para compreender os problemas ambientais e sociais, já que o relevo é fator preponderante para o plantio e/ou povoamento. Neste contexto, o presente trabalho tem por objetivo fazer um levantamento preliminar da geomorfologia do Córrego do Cerrado que drena o município de Canápolis/MG, por meio de revisões bibliográfica e campo

Inclusive electron scattering in a relativistic Green function approach

A relativistic Green function approach to the inclusive quasielastic (e,e') scattering is presented. The single particle Green function is expanded in terms of the eigenfunctions of the nonhermitian optical potential. This allows one to treat final state interactions consistently in the inclusive and in the exclusive reactions. Numerical results for the response functions and the cross sections for different target nuclei and in a wide range of kinematics are presented and discussed in comparison with experimental data.Comment: 12 pages, 7 figures, REVTeX

Supersymmetric Relations Among Electromagnetic Dipole Operators

Supersymmetric contributions to all leptonic electromagnetic dipole operators have essentially identical diagramatic structure. With approximate slepton universality this allows the muon anomalous magnetic moment to be related to the electron electric dipole moment in terms of supersymmetric phases, and to radiative flavor changing lepton decays in terms of small violations of slepton universality. If the current discrepancy between the measured and Standard Model values of the muon anomalous magnetic moment is due to supersymmetry, the current bound on the electron electric dipole moment then implies that the phase of the electric dipole operator is less than $2 \times 10^{-3}$. Likewise the current bound on $\mu \to e \gamma$ decay implies that the fractional selectron-smuon mixing in the left-left mass squared matrix, \delta m_{\smuon \selectron}^2 / m_{\slepton}^2, is less than $10^{-4}$. These relations and constraints are fairly insensitive to details of the superpartner spectrum for moderate to large $\tan \beta$.Comment: Latex, 38 pages, 2 figure
