One loop corrections to coupling constants in string effective field theory
In the framework of a recently proposed method for computing exactly string amplitudes regularized in the infra-red, I determine the one-loop correlators for auxiliary fields in the symmetric Z_2\times Z_2 orbifold model. The D-field correlation function turns out to give the one-loop corrections fo...
