We study the multiloop amplitudes of the light-cone gauge closed bosonic string field theory for d ≠ 26. We show that the amplitudes can be recast into a BRST invariant form by adding a nonstandard worldsheet theory for the longitudinal variables X ± andthereparametrizationghostsystem. Theresultsobtainedinthispaperforbosonic strings provide a first step towards the examination whether the dimensional regularization works for the multiloop amplitudes of the light-cone gauge superstring field theory.
