Query: Massive mixed symmetry field dynamics in open bosonic string theory   We consider the sigma-model description of an open string interacting with
massive fields of the fourth (third massive) level. Equations of motion for the
background fields are obtained by demanding that the renormalized operator of
the energy-momentum tensor trace vanishes.
