We derive a simple prescription for including beyond-linear halo bias within the standard, analytical halo-model power spectrum calculation. This results in a corrective term that is added to the usual two-halo term. We measure this correction using data from N-body simulations and demonstrate that it can boost power in the two-halo term by a factor of ∼2 at scales k∼0.7 h Mpc^-1, with the exact magnitude of the boost determined by the specific pair of fields in the two-point function.
