Two-loop β-function for the generalized bosonic sigma model
Description
We independently compute: (i) the order α' terms in the effective action for the massless fields in the Bose string theory and (ii) the two-loop β-function in the corresponding two-dimensional σ-model. It is proved that the ''massless string fields equations of motion equal the σ-model Weyl invariance conditions'' conjecture is true to the given order. (orig.)
