Generalized Symmetries of Massless Free Fields on Minkowski Space⋆
نویسنده
چکیده
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 yield a complete classification of generalized symmetries of the Dirac–Weyl neutrino equation, Maxwell’s equations, and the linearized gravity equations.

A recent complete, explicit classification of all locally constructed symmetries and currents for free spinorial massless spin s fields on Minkowski space is summarized and extended to give a classification of all covariant symmetry operators and conserved tensors. The results, for physically interesting cases, are also presented in tensorial form for electromagnetic and graviton fields (s = 1,...
متن کاملMixed-Symmetry Massless Fields in Minkowski space Unfolded
The unfolded formulation for arbitrary massless mixed-symmetry bosonic and fermionic fields in Minkowski space is constructed. The unfolded form is proved to be uniquely determined by the requirement that all gauge symmetries are manifest. The unfolded equations have the form of a covariant constancy condition. The gauge fields and gauge parameters are differential forms with values in certain ...
متن کاملHOW MASSLESS ARE MASSLESS FIELDS IN AdSd
Massless fields of generic Young symmetry type in AdSd space are analyzed. It is demonstrated that in contrast to massless fields in Minkowski space whose physical degrees of freedom transform in irreps of o(d−2) algebra, AdS massless mixed symmetry fields reduce to a number of irreps of o(d− 2) algebra. From the field theory perspective this means that not every massless field in flat space ad...
متن کاملClassification of Generalized Symmetries of the Yang-mills Fields with a Semi-simple Structure Group
A complete classification of generalized symmetries of the Yang-Mills equations on Minkowski space with a semi-simple structure group is carried out. It is shown that any generalized symmetry, up to a generalized gauge symmetry, agrees with a first order symmetry on solutions of the Yang-Mills equations. Let g = g1+ · · ·+gn be the decomposition of the Lie algebra g of the structure group into ...
متن کاملdS/CFT Correspondence from a Holographic Description of Massless Scalar Fields in Minkowski Space-Time
We study a one-to-one map between massless scalar fields on d+1 dimensional Minkowski (Euclidean) space time and scalar fields on d+1 dimensional De Sitter (Euclidean AdS) space. We solve the Klein-Gordon equation for massless scalar field in terms of initial data on the hypersurface t=0 which is isomorphic to the boundary of dS (AdS) space. By inserting these solutions into the action of massl...
