摘要：
We present a four parameter family of classical string solutions in AdS(3) x S-3, which end along a light-like tetragon at the boundary of AdS(3) and carry angular momentum along two cycles on the sphere. The string surfaces are space-like and their projections on AdS(3) and on S-3 have constant mean curvature. The construction is based on the Pohlmeyer reduction of the related sigma model. After embedding in AdS(5) x S-5, we calculate the regularized area and analyze conserved charges. Comments on possible relations to scattering amplitudes are presented. We also sketch time-like versions of our solutions.
