Title : ( Gravitational couplings on D-brane revisited )
Authors: Ahmad Ghodsi Mahmoudzadeh , Ghadir Jafari ,
Full TextAbstract
Gravitational couplings in bulk space-time include those terms which are xed by scattering amplitude of strings and ambiguous terms that are coming from the eld rede nitions. These eld rede nitions can be xed in the bulk by ghost-free condition. In this paper we have revised the e ective gravitational couplings on D-branes by including the eld rede nitions. We nd the gravitational e ective action up to a'^2-order.
