Tduality of α^{′}correction to DBI action at all orders of gauge field
Abstract
By explicit calculations of fourfield couplings, we observe that the higher derivative corrections to the DBI action in flat spacetime, can be either in a covariant form or in a Tduality invariant form. The two forms are related by a noncovariant field redefinition. Using this observation, we then propose a noncovariant but Tduality invariant action which includes all orders of massless fields and has two extra derivatives with respect to the DBI action.
