Worldsheet CFTs for Flat Monodrofolds

  title={Worldsheet CFTs for Flat Monodrofolds},
  author={Simeon Hellerman and Johannes Walcher},
We resolve a puzzle in the theory of strings propagating on locally flat spacetimes with nontrivial Wilson lines for stringy ZZN gauge symmetries. We find that strings probing such backgrounds are described by consistent worldsheet CFTs. The level mismatch in the twisted sectors is compensated by adjusting the quantization of momentum of strings winding around the Wilson line direction in units of 1/RN rather than 1/RN , as might have been classically expected. We demonstrate in various… CONTINUE READING
