D-branes in the light-cone gauge and broken symmetries


Boundary states for D-branes are constructed using the light cone gauge. The D-brane breaks half the spacetime supersymmetry giving rise to fermionic zero modes living on the brane. The nonlinear realization of the broken supersymmetry on the open string degrees of freedom is analysed and the influence of boundary terms coming from closed string vertex operators is discussed.Comment: 8 pages, Latex, uses sprocl.sty, Contribution to the workshop "Gauge Theories, Applied Supersymmetry and Quantum Gravity", London, Imperial College, July 199
