We compute the dynamical structure factor of the spin-½ triangular Heisenberg model using Schwinger Boson Mean Field Theory. We find that the reconstructed dispersion, resulting from a non trivial redistribution of the spectral weight, agrees quite well with the spectrum recently found with series expansion
