Lightcone superstring in /AdS spacetime
Abstract
We consider fixing the bosonic lightcone gauge for string in AdS space in the phase space framework, i.e., by choosing x ^{+}=τ , and by choosing σ so that P ^{+} is distributed uniformly (its density P^{+} is independent of σ). We discuss classical bosonic string in AdS _{d} and superstring in AdS _{5}×S ^{5}. In the latter case the starting point is the action found in hepth/0007036, where the κsymmetry is fixed by a fermionic lightcone type gauge. We derive the lightcone Hamiltonian in the AdS _{5}×S ^{5} case and in the case of superstring in AdS _{3}×S ^{3}. We also obtain a realization of the generators of the basic superalgebra psu(2,24) in terms of AdS _{5}×S ^{5} superstring coordinate 2d fields in the lightcone gauge.
