Higgs Model with Radial Excitations and Mode Correlation Problem
نویسنده
چکیده
The phase diagram of the Z2 lattice Higgs model is studied without freezing out the radial excitations. Comparing the results of three meanfield models, effects of mode-mode correlations on the phase diagram are investigated. The second order end point of the first order transition line between the Higgs and the confinement phase, observed at the frozen limit of the radial mode, is shown to reach the strong gauge coupling limit (/39=0) for sufficiently small quartic self-coupling of the Higgs scalar.

متن کاملNew String Excitations in the Two-Higgs Standard Model
The effective theory of electroweak interactions may contain more than the single Higgs doublet of the minimal Standard Model. Theoretical arguments in favour of an extended Higgs sector [1] include supersymmetry and string theory, as well as the possibility of electroweak baryogenesis [2]. Extra Higgs scalars give rise to a richer spectrum of non-perturbative excitations, such as membrane defe...

The order-disorder duality structure is exploited in order to obtain a quantum description of anyons and vortices in: a) the Maxwell theory; b) the Abelian Higgs Model; c) the Maxwell-Chern-Simons theory; d) the Maxwell-Chern-Simons-Higgs theory. A careful construction of a charge bearing order operator(σ) and a magnetic flux bearing disorder operator (vortex operator) (μ) is performed, paying ...

In this paper, the radial breathing mode (RBM) frequencies of multi-walled carbon nanotubes (MWCNTs) are obtained based on the multiple-elastic thin shell model. For this purpose, MWCNT is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der Waals (vdW) forces between two adjacent tubes. Lennard-Jones potential is used to calculate the vdW ...
