HOW 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 کاملMassless arbitrary spin fields in AdS 5
Free arbitrary spin massless and massive self-dual fields propagating in AdS 5 are investigated. We study totally symmetric and mixed symmetry fields on an equal footing. Light-cone gauge action for such fields is constructed. As an example of application of light-cone formalism we discuss AdS/CF T correspondence for massless arbitrary spin AdS fields and corresponding boundary operators at the...
متن کاملMassless Particles and Fields ”
Free fields of massless particles transforming covariantly under the Poincare group are constructed. The allowed infinite and finite dimensional representations of the Lorentz group are obtained. The wave functions are calculated in these representations in various bases u The commutation rules are computed, and turn out to be non-local for any infinite dimens ional fields. The transformation l...
متن کاملMassless fields in scalar-tensor cosmologies.
We derive exact Friedmann–Robertson–Walker cosmological solutions in general scalar–tensor gravity theories, including Brans–Dicke gravity, for stiff matter or radiation. These correspond to the long or short wavelength modes respectively of massless scalar fields. If present, the long wavelength modes of such fields would be expected to dominate the energy density of the universe at early time...
متن کاملSTAR - PRODUCT AND MASSLESS FREE FIELD DYNAMICS IN AdS 4
Generic solution of free equations for massless fields of an arbitrary spin in AdS 4 is built in terms of the star-product algebra with spinor generating elements. A class of " plane wave " solutions is described explicitly.
