Generalized Symmetries of Massless Free Fields on Minkowski Space⋆
A complete and explicit classification of generalized, or local, symmetries of massless free fields of spin s ≥ 1/2 is carried out. Up to equivalence, these are found to consists of the conformal symmetries and their duals, new chiral symmetries of order 2s, and their higher-order extensions obtained by Lie differentiation with respect to conformal Killing vectors. In particular, the results yi...
متن کاملSymmetries and solutions of equations describing force-free magnetic fields
New analytical results for two-dimensional force-free fields are presented. First, a number of exact solutions for force-free fields described by Liouville equation are given and their physical relevance for laboratory and astrophysical plasmas is discussed. Subsequently, Lie point symmetries of Liouville equation are reviewed and Lie point symmetries of the equation describing helically symmet...
متن کاملGroup Quantization on Configuration Space: Gauge Symmetries and Linear Fields
A new, configuration-space picture of a formalism of group quantization, the GAQ formalism, is presented in the context of a previous, algebraic generalization. This presentation serves to make a comprehensive discussion in which other extensions of the formalism, principally to incorporate gauge symmetries, are developed as well. Both images are combined in order to analyse, in a systematic ma...
متن کاملGauge Symmetries and Vector-Boson Self Interactions
The discovery of the W and Z bosons at the CERN Spp̄S in 1983 (1) began the era of the weak vector boson. It opened with a bang, earning a Nobel prize for the discovery of the particles and the development of the machine that made it possible (2). That era is now in its maturity, with precision studies of Z bosons taking place at the CERN LEP and SLAC SLC ee colliders, and studies of both Z and ...
متن کاملSymmetries in the Interacting Boson Model
We study the energy level statistics of the states in U(5) and O(6) dynamical symmetries of the interacting boson model and the high spin states with backbending in U(5) symmetry. In the calculations, the degeneracy resulting from the additional quantum number is eliminated manually. The calculated results indicate that the finite boson number N effect is prominent. When N has a value close to ...
