On RR couplings on D-branes at order $O({\alpha }^{\prime 2})$

Mohammad R. Garousi, Mozhgan Mir

Recently, it has been found that there are couplings of the RR field strength $F^{(p)}$ and the B-field strength $H$ on the world volume of D${}_p$-branes at order $\mathcal{O}({\alpha }^{\prime 2})$.…
