Quantization of Bosonic String Model in 26+2-dimensional Spacetime
Takuya Tsukioka, Yoshiyuki Watabiki
Abstract
We investigate the quantization of the bosonic string model which has a local U(1)V * U(1)A gauge invariance as well as the general coordinate and Weyl invariance on the world-sheet. The model is quantized by Lagrangian and Hamiltonian BRST formulations á la Batalin, Fradkin and Vilkovisky and noncovariant light-cone gauge formulation. Upon the quantization the model turns out to be formulated consistently in 26+2-dimensional background spacetime involving two time-like coordinates.
