Spectrum of Higher Derivative 6D Chiral Supergravity    [PDF]

Y. Pang, C. N. Pope, E. Sezgin
Gauged off-shell Maxwell-Einstein supergravity in six dimensions with N=(1,0) supersymmetry has a higher derivative extension afforded by supersymmetrized Riemann squared term. This theory admits supersymmetric Minkowski x S^2 compactification with a U(1) monopole of unit charge on S^2. We determine the full spectrum the theory on this background. We also determine the spectrum on a non-supersymmetric version of this compactification in which the monopole charge is different than unity and find the peculiar feature that that there are massless gravitini in a presentation of the S^2 isometry group determined by the monopole charge.
