dc.description.abstract | Motivated by the notorious di culties in determining the rst quantum corrections
to the spectrum of short strings in
AdS

from rst principles, we study closed
bosonic strings in this background employing a static gauge. In this gauge the
world-sheet Hamiltonian density is constant along the extension of the string and
directly proportional to the square of the spacetime energy. We quantize this sys-
tem in a minisuperspace approach, in which we consider only a single
AdS

mode excitation next to an arbitrary particle like zero-mode contribution in the full

background. We determine the quantum spectrum using this method to
the next-to-next-to-leading order in the large 't Hooft coupling expansion. We ar-
gue for an ordering prescription which should arise from supersymmetrization and
indeed recover the integrability based predictions for the spectrum of the lightest
excitation, dual to the Konishi eld scaling dimensions. The higher excitations
fail to agree, but this is shown to be a consequence of the string mode truncation
employed. Despite this simple setup, our system reveals intriguing features, such
as a close connection to particles in
AdS 6 , classical integrability and preservation
of the isometries of
