Becchi-Rouet-Stora-Tyutin quantization of a soliton model in 2+1 dimensions
J. P. Garrahan, L. M. Kruczenski, C. L. Schat +2
The Becchi-Rouet-Stora-Tyutin (BRST) method is applied to the quantization of the solitons of the non-linear model in dimensions. We show that this method allows for a…
Influence of Strings with Axionic Content on the Polarization of Extragalactic Sources
Luis Masperi, Sandra Savaglio
It is shown that the axion concentrated in electroweak strings which are consequently stabilized may produce a rotation of the polarization angle of radiation from extragalactic so…
Multiparticle Reactions with Spatial Anisotropy
Vladimir Privman, Enrique Burgos, Marcelo D. Grynberg
We study the effect of anisotropic diffusion on the one-dimensional annihilation reaction kA->inert with partial reaction probabilities when hard-core particles meet in groups of k…
Stability of Modified Electroweak Strings
Luis Masperi, Ariel Megevand
We discuss the stability of an electroweak string with axions in its core, which give to the configuration a quasi-topological property, and compare it with other modifications usi…
Cyclic Permutations in Kazama-Suzuki String Models
G. Aldazabal, I. Allekotte, E. Andres +1
Moddings by cyclic permutation symmetries are performed in 4-dimensional strings, built up from N=2 coset models of the type . For some exemplifying…
Lambda(1405) in the Bound State Soliton Model
C. L. Schat, N. N. Scoccola, C. Gobbi
The strong and electromagnetic properties of the Lambda(1405) hyperon are studied in the framework of the bound state soliton model. We explicitly evaluate the strong coupling cons…
