UV asymptotically free QED as a broken YM theory in the unitary gauge
G. Bimonte, R. Iengo, G. Lozano
We compute the -function of a YM theory, broken to , by evaluating the coupling constant renormalization in the broken phase. We perform the calculation in the unitary gau…
Finite Fermion Density Effects on the Electroweak String
G. Bimonte, G. Lozano
We consider an Electroweak string in the background of a uniform distribution of cold fermionic matter. As a consequence of the fermion number non-conservation in the Weinberg-Sala…
Vortex Solutions in Two-Higgs-Doublet Systems
G. Bimonte, G. Lozano
We analyze the existence of string-like defects in a two-Higgs-doublet system having as gauge group. We are able to show that, when c…
Differential Regularization of a Non-relativistic Anyon Model
D. Z. Freedman, G. Lozano, N. Rius
Differential regularization is applied to a field theory of a non-relativistic charged boson field with self-interaction and coupling to a statistics-changing…
Extended Superconformal Galilean Symmetry in Chern-Simons Matter Systems
M. Leblanc, G. Lozano, H. Min
We study the nonrelativistic limit of the supersymmetric Chern-Simons matter system. We show that in addition to Galilean invariance the model admits a set of symmetries gene…
