On The Complete Seiberg-Witten Map For Theories With Topological Terms
L. C. Q. Vilar, O. S. Ventura, R. L. P. G. Amaral +2
The SW map problem is formulated and solved in the BRST cohomological approach. The well known ambiguities of the SW map are shown to be associated to distinct cohomological classe…
Fragmentation Experiment and Model for Falling Mercury Drops
P. M. C. de Oliveira, C. A. F. Leite, C. V. Chianca +2
The experiment consists of counting and measuring the size of the many fragments observed after the fall of a mercury drop on the floor. The size distribution follows a power-law f…
Island coarsening in one-dimensional models with partially and completely reversible aggregation
Anna Chame, F. D. A. Aarao Reis
Using computer simulations and scaling ideas, we study one-dimensional models of diffusion, aggregation and detachment of particles from islands in the post-deposition regime, i. e…
Casimir bag energy in the stochastic approximation to the pure QCD vacuum
C. D. Fosco, L. E. Oxman
We study the Casimir contribution to the bag energy coming from gluon field fluctuations, within the context of the stochastic vacuum model (SVM) of pure QCD. After formulating the…
Elastic Scattering and Total Reaction Cross Section for the 6He + 27Al System
E. A. Benjamim, A. Lepine-Szily, D. R. Mendes Junior +14
The elastic scattering of the radioactive halo nucleus 6He on 27Al target was measured at four energies close to the Coulomb barrier using the RIBRAS (Radioactive Ion Beams in Braz…
A supercritical series analysis for the generalized contact process with diffusion
W. G. Dantas, J. F. Stilck
We study a model that generalizes the CP with diffusion. An additional transition is included in the model so that at a particular point of its phase diagram a crossover from the d…
