We construct the six-dimensional Lagrangian for the massless twisted open strings with one end-point ending on a stack of D5 and the other on a stack of D9 branes, interacting with the gauge multiplets living respectively on the D5 and D9 branes. It is first obtained by uplifting to six dimensions the four-dimensional Lagrangian of the hypermultiplet and manifestly exhibits an SU(2) symmetry. We show by an explicit calculation that it is supersymmetric in six dimensions and then we check… Expand
The classical solution for the Bosonic string in the presence of three D-branes rotated by arbitrary SO(4) elements
Abstract We consider the classical instantonic contribution to the open string configuration associated with three D-branes with relative rotation matrices in SO ( 4 ) which corresponds to theExpand
Light cone quantization and interactions of a new closed bosonic string inspired to D1 string
Abstract We quantize the bosonic part of the D 1 string with closed boundary conditions on the light cone and we consider the U ( 1 ) worldsheet gauge field a dynamical variable. We compute alsoExpand
Canonical quantization of a string describing $N$ branes at angles
Abstract We study the canonical quantization of a bosonic string in presence of N twist fields. This generalizes the quantization of the twisted string in two ways: the in and out states are notExpand

On the gauge chosen by the bosonic open string
