Symmetry breaking in non-commutative cut-off field theories

چکیده
The relation between symmetry breaking in non-commutative cut-off field theories and transitions to inhomogeneous phases in condensed matter and in finite density QCD is discussed. The non-commutative dynamics, with its peculiar infrared-ultraviolet mixing, can be regarded as an effective description of the mechanisms which lead to inhomogeneous phase transitions and a roton-like excitation spectrum.

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...
متن کاملNon-Commutativity and Unitarity Violation in Gauge Boson Scattering
We examine the unitarity properties of spontaneously broken non-commutative gauge theories. We find that the symmetry breaking mechanism in the non-commutative Standard Model of Chaichian et al. leads to an unavoidable violation of tree-level unitarity in gauge boson scattering at high energies. We then study a variety of simplified spontaneously broken non-commutative theories and isolate the ...
متن کاملThe Renormalization of Non-Commutative Field Theories in the Limit of Large Non-Commutativity
We show that renormalized non-commutative scalar field theories do not reduce to their planar sector in the limit of large noncommutativity. This follows from the fact that the RG equation of the Wilson-Polchinski type which describes the genus zero sector of non-commutative field theories couples generic planar amplitudes with non-planar amplitudes at exceptional values of the external momenta...
متن کاملDynamical symmetry breaking on a brane with bulk gauge theory
We analyze a structure of dynamical chiral symmetry breaking in orbifold gauge theories with matter fields (fermions) on the fixed point. We find that the boundary chiral phase structure of QED and QCD on the orbifold is quite nontrivial depending on the bulk constitution, and we claim that particular attention should be given to the dynamically generated masses in various kinds of phenomenolog...
متن کاملNoncommutativity and Spontaneously Broken Gauge Theories
We examine the spontaneous symmetry breaking of gauge theories in the framework of noncommutative field theory. We consider a noncommutative U(2) Higgs model with matter in the adjoint representation, that is the simplest example of a noncom-mutative gauge theory that is both classically well-defined in R ξ gauges and has an interacting commutative limit. In the ungauged global limit, the quant...
