A note on unparticle in lower dimensions
arXiv:0807.0338 · doi:10.1016/j.physletb.2008.08.055
Abstract
Using the gauge-invariant but path-dependent variables formalism, we examine the effect of the space-time dimensionality on a physical observable in the unparticle scenario. We explicitly show that long-range forces between particles mediated by unparticles are still present whenever we go over into lower dimensions.
