Deconfinement transition in three-dimensional compact U(1) gauge theories coupled to matter fields.
It is shown that permanent confinement in three-dimensional compact U(1) gauge theory can be destroyed by matter fields in a deconfinement transition. This follows from a nontrivial infrared fixed point caused by matter, and an anomalous scaling dimension of the gauge field. This leads to a logarithmic interaction between the defects of the gauge fields, which form a gas of magnetic monopoles. ...
متن کاملThe Supersymmetric Wess - Zumino Action and U ( 1 ) Gauge Fields
The supersymmetric effective action is constructed which when varied _ under gauge groups containing explicit U(1) factors reproduces the mixed gauge field contribution to the SU(N) anomaly while being U(1) invariant. It constitutes a generalization of the supersymmetric Wess-Zumino action. The form of the supersymmetric mixed anomaly is also discussed. Submitted to Physics Letters * Work suppo...
متن کاملLocalized U ( 1 ) Gauge Fields , Millicharged Particles , and Holography
We consider U(1) gauge fields in a slice of AdS5 with bulk and boundary mass parameters. The zero mode of a bulk U(1) gauge field can be localized either on the UV or IR brane. This leads to a simple model of millicharged particles in which fermions can have arbitrarily small electric charge. In the electroweak sector we also discuss phenomenological implications of a localized U(1)Y gauge boso...
متن کاملDomain-wall fermions with U(1) dynamical gauge fields.
We have carried out a numerical simulation of a domain-wall model in (2+1)dimensions, in the presence of a dynamical gauge field only in an extra dimension, corresponding to the weak coupling limit of a ( 2-dimensional ) physical gauge coupling. Using a quenched approximation we have investigated this model at βs(= 1/g 2 s ) = 0.5 ( “symmetric” phase), 1.0, and 5.0 (“broken” phase), where gs is...
متن کاملMinimal U(1) gauge fields in two dimensions
Gribov copies of the vacuum in two dimensional compact U(1) lattice gauge models are constructed. On the basis of this a gauge fixing algorithm is developped, wich finds the minimum of the sum of link field squares. Numerical experience in a two dimensional Higgs model with fixed length scalar field is reported and the extension to three and four dimensional U(1) and four dimensional SU(2) gaug...
