In this talk, we study the precession of the orbit of the half bps black holes in N=8 Supergravity. In GR, we know that the orbits of the black holes precess which is due to the higher loop order correction to the 1/r potential. As a matter of fact, lack of precession in the N=8 supergravity orbit corresponds to an extra symmetry which makes the system integrable and indeed supports the integrability conjecture for this theory. In this work we show that up to the 1st loop order there is no precession caused by correction to the potential for any masses and central charges of the black holes. In addition, in the probe limit we observe that the “no precession” result holds to all loop order. Finally, in the process of finding one-loop correction, we will also see that the “No triangle hypothesis” [hep-th/0610043] and “no precession” are closely related.
