Abstract: | We show that the K–K spectrum of IIB string on
is described by “twisted chiral”
superfields, naturally described in “harmonic superspace”, obtained by taking suitable gauge singlets polynomials of the D3-brane boundary
superconformal field theory.To each p-order polynomial is associated a massive K–K short representation with
states. The
quadratic polynomial corresponds to the “supercurrent multiplet” describing the “massless” bulk graviton multiplet. |
