Relativistic scalar Aharonov-Bohm scattering
M. Gomes, J. M. C. Malbouisson, A. G. Rodrigues +1
We discuss the scattering of relativistic spin zero particles by an infinitely long and arbitrarily thin solenoid. The exact solution of the first-quantized problem can be obtained…
A Consistent Noncommutative Field Theory: the Wess-Zumino Model
H. O. Girotti, M. Gomes, V. O. Rivelles +1
We show that the noncommutative Wess-Zumino model is renormalizable to all orders of perturbation theory. The noncommutative scalar potential by itself is non-renormalizable but th…
Renormalization Group Study of Chern-Simons Field Coupled to Scalar Matter in a Modified BPHZ Subtraction Scheme
L. C. de Albuquerque, M. Gomes, A. J. da Silva
We apply a soft version of the BPHZ subtraction scheme to the computation of two-loop corrections from an Abelian Chern-Simons field coupled to (massive) scalar matter with a $λ(Φ^…
Non-Abelian Aharonov-Bohm Scattering of Spin 1/2 Particles
M. Gomes, L. C. Malacarne, A. J. da Silva
We study the low energy regime of the scattering of two fermionic particles carrying isospin 1/2 and interacting through a non-Abelian Chern-Simons field. We calculate the one-loop…
A Renormalization Group Study of the Model coupled to a Chern-Simons Field
V. S. Alves, M. Gomes, S. L. V. Pinheiro +1
We consider the model of a massless charged scalar field, in (2+1) dimensions, with a self interaction of the form and interacting with a Chern Simons field. We…
