Regular and chaotic interactions of two BPS dyons at low energy
Ricardo Fariello, Hilmar Forkel, Gastao Krein
We identify and analyze quasiperiodic and chaotic motion patterns in the time evolution of a classical, non-Abelian Bogomol'nyi-Prasad-Sommerfield (BPS) dyon pair at low energies.…
Pion Electromagnetic Form Factor up to 10 [GeV/]^2
J. P. B. C. de Melo
The light-front approach is applied to calculate the electromagnetic current for quark-antiquark bound states for the pion. The pion electromagnetic form factor is obtnaide from th…
Kaon Eletromagnetic Form Factor in the Light-Front Formalism
Fabiano P. Pereira, J. P. B. C. de Melo, T. Frederico +1
Numerical calculations are performed and compared to the experimental data for the electromagnetic form factor of the kaon, which is extracted from both components of the electroma…
Extended Cahill-Glauber formalism for finite dimensional spaces: I. Fundamentals
M. Ruzzi, M. A. Marchiolli, D. Galetti
The Cahill-Glauber approach for quantum mechanics on phase-space is extended to the finite dimensional case through the use of discrete coherent states. All properties and features…
Scalar and Vector Massive Fields in Lyra's Manifold
R. Casana, C. A. M. de Melo, B. M. Pimentel
The problem of coupling between spin and torsion is analysed from a Lyra's manifold background for scalar and vector massive fields using the Duffin-Kemmer-Petiau (DKP) theory. We…
Superspace Type II 4D Supergravity from Type II Superstring
Daniel L. Nedel
We derive the equations of motion of type II 4D supergravity in superspace. This is achieved by coupling the Type II Berkovits' hybrid superstring to an N=2 curved background and r…
