Classical and Quantized Tensionless Strings

  title={Classical and Quantized Tensionless Strings},
  author={Jan Isberg and Ulf Lindstr{\"o}m and B. Sundborg},
From the ordinary tensile string we derive a geometric action for the tensionless (T = 0) string and discuss its symmetries and field equations. The Weyl symmetry of the usual string is shown to be replaced by a global space-time conformal symmetry in the T → 0 limit. We present the explicit expressions for the generators of this group in the light-cone gauge. Using these, we quantize the theory in an operator form and require the conformal symmetry to remain a symmetry of the quantum theory… CONTINUE READING
