A note on spin-2 fields in curved backgrounds
We reconsider the consistency constraints on a free massless symmetric rank 2 tensor field in a background and confirm that they uniquely require it to be the linear deviation about (cosmological) Einstein gravity. Neither adding non-minimal higher derivative terms nor changing the gauge transformations by allowing terms non-analytic in the cosmological constant alters this fact. PACS numbers: ...
متن کاملBranes: from Free Fields to General Backgrounds
Motivated by recent developments in string theory, we study the structure of boundary conditions in arbitrary conformal field theories. A boundary condition is specified by two types of data: first, a consistent collection of reflection coefficients for bulk fields on the disk; and second, a choice of an automorphism ω of the fusion rules that preserves conformal weights. Non-trivial automorphi...

متن کاملApplications of chiral supersymmetry for spin fields in self-dual backgrounds
Due to chiral supersymmetry the (nonzero mode) spectral and symmetry properties of a 4-dimensional, self-dual Dirac-Yang-Mills operator D / can be recovered from those of the corresponding scalar Laplacian D. It is shown that a similar result holds for higher spins, and that in the 4-vector case the supersymmetric partners are −D14 and the fluctuation operator. The reduction to D is used to sim...
متن کاملTransverse Symmetry and Spin-3/2 Fields
We study the possible covariant Lagrangians that describe the propagation of pure spin3/2 particles. We show that, apart from the well-known Rarita-Schwinger Lagrangian, there is another possibility where the field is described by a γ-traceless combination and that both Lagrangians yield the same physical predictions for the interaction of conserved sources. We also prove that for the case when...
