Abstract: (arXiv)
We study how the dimensional regularization works in the light-cone gauge string field theory. We show that it is not necessary to add a contact term to the string field theory action as a counter term in this regularization at least at the tree level. We also investigate the one-loop amplitudes of the bosonic theory in noncritical dimensions and show that they are modular invariant.- regularization: dimensional
- field theory: string
- field theory: action
- invariance: modular
- boson: field theory
