Transverse Invariant Higher Spin Fields
It is shown that a symmetric massless bosonic higher-spin field can be described by a traceless tensor field with reduced (transverse) gauge invariance. The Hamiltonian analysis of the transverse gauge invariant higher-spin models is used to control a number of degrees of freedom.
متن کاملKinematics of Higher-spin Fields
This dissertation argues a quantum theory for higher-spin fields. Causality is discussed in both classical and quantum senses in a field theory. Renormalizability is also considered. Equations of motion are derived from a generalised concept of linearised Christoffel symbols for these higher-spin fields. It is seen that a minimally-coupled Rarita-Schwinger field violates causality, and that sup...
متن کاملClassical Nambu-Goldstone fields
It is shown that a Nambu-Goldstone (NG) field may be coherently produced by a large number of particles in spite of the fact that the NG bosons do not couple to flavor conserving scalar densities like ψ̄ψ. If a flavor oscillation process takes place the phases of the pseudo-scalar or flavor violating densities of different particles do not necessarily cancel each other. The NG boson gets a macro...
متن کاملGeometric Lagrangians for massive higher-spin fields
Lagrangians for massive, unconstrained, higher-spin bosons and fermions are proposed. The idea is to modify the geometric, gauge invariant Lagrangians describing the corresponding massless theories by the addition of suitable quadratic polynomials. These polynomials provide generalisations of the Fierz-Pauli mass term containing all possible traces of the basic field. No auxiliary fields are ne...
متن کاملHigher-Spin Gauge Fields and Duality
We review the construction of free gauge theories for gauge fields in arbitrary representations of the Lorentz group in D dimensions. We describe the multi-form calculus which gives the natural geometric framework for these theories. We also discuss duality transformations that give different field theory representations of the same physical degrees of freedom, and discuss the example of gravit...
