Geometric Formulation for Partially Massless Fields
The manifestly gauge invariant formulation for free symmetric higher-spin partially massless fields in (A)dSd is given in terms of gauge connections and linearized curvatures that take values in the irreducible representations of (o(d−1, 2)) o(d, 1) described by two-row Young tableaux, in which the lengths of the first and second row are, respectively, associated with the spin and depth of part...
متن کاملProduction of massless fermions during inflation
We compute the one loop self energy, in a locally de Sitter background, for a massless fermion which is Yukawa-coupled to a massless, minimally coupled scalar. We then solve the modified Dirac equation resulting from inclusion of the self energy. We find fasterthan-exponential growth in the fermion wave function, consistent with the production of fermions through a process in which a scalar and...
متن کاملPartially Massless Spin-2 Fields in String Generated Models
In cosmological backgrounds, there can be ’partially massless’ higher spin fields which have fewer degrees of freedom than their massive partners. The equations for the partially massless spin-2 fields are usually taken to be the linearized Einstein equations augmented with a ’tuned’ Pauli-Fierz mass. Here, we add more powers of curvatures and show that for the string-generated Einstein-Gauss-B...
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 کاملPM1⁄4EM? Partially massless duality invariance
is almost coeval with Maxwell’s equations themselves, although a proof of its validity awaited over a century [1,2]. In addition to countless generalizations of ‘‘duality’’ in field and string theory, it has led to an enormous variety of more precise analogs, in particular to spin 2 [2,3], then to all free massless (integer or half-integer) spin s > 0 systems in flat space [4,5]. In de Sitter (...
