Effective action of type II superstring theories at order α′3: NS-NS couplings
Abstract Recently, it has been shown that the minimum number of gauge invariant couplings for B-field, metric and dilaton at order α′ 3 is 872. These couplings, in a particular scheme, appear in 55 different structures. In this paper, up to an overall factor, we fix all parameters in type II superti...
