Remarks on Koba-nielsen-olesen Scaling
It is shown that there is a second properly normalized KNO scaling function, nPn(n/n̄) = φ(z), which has certain advantages in the analysis of KNO scaling. First, the nPn are not influenced by the statistical and systematic uncertainties of n̄ hence φ(z) provides more selective power than the original KNO scaling function n̄Pn(n/n̄) = ψ(z). Second, the new scaling function generates scale parameter...
متن کاملOn the Asymptotics of Nielsen-Olesen Vortices
We investigate analytically and numerically the asymptotic behavior of the Nielsen-Olesen vortex solutions and show that they approach their asymptotic values exponentially but with exponents that differ from the ones quoted in the literature. In particular, it is shown that for values of the Higgs self-coupling that are larger than a critical value, both the Higgs field and the gauge field app...
متن کاملExtrinsic Curvature Dependence of Nielsen-olesen Strings
It is shown how to treat the degrees of freedom of Nielsen-Olesen vortices in the 3+ 1dimensional U(1) higgs model by a collective coordinate method. In the london limit, where the higgs mass becomes infinite, the gauge and goldstone degrees of freedom are integrated out, resulting in the vortex world-sheet action. Introducing an ultraviolet cut-off mimics the effect of finite higgs mass. This ...
متن کاملNielsen-Olesen vortices in noncommutative space
We construct an exact regular vortex solution to the self-dual equations of the Abelian Higgs model in non-commutative space for arbitrary values of θ. To this end, we propose an ansatz which is the analogous, in Fock space, to the one leading to exact solutions for the Nielsen-Olesen vortex in commutative space. We compute the flux and energy of the solution and discuss its relevant properties.
متن کاملQuantum oscillations of self-dual Abrikosov-Nielsen-Olesen vortices
In this paper we present some new results on the quantization of the self dual multi-vortex solutions of the Abelian Higgs model. We also take the opportunity to offer a detailed description of the concepts and techniques that allowed us to compute the one-loop quantum correction to the mass of self-dual Abrikosov-Nielsen-Olesen vortices with one quantum of magnetic flux in the Rapid Communicat...
