In this paper we first introduce the full expression of the curvature tensor of a real hypersurface M in complex hyperbolic two-plane Grassmannians SU 2, m/S (U 2⋅ U m), m≥ 2 from the equations of Gauss. Next we derive a new formula for the Ricci tensor of M in SU 2, m/S (U 2⋅ U m). As an application of this result we prove that there do not exist Einstein Hopf or Q⊥-invariant Einstein real hypersurfaces in SU 2, m/S (U 2⋅ U m).
