      abstract     = {We analyze the dark matter power spectrum at three-loop
                      order in standard perturbation theory of large scale
                      structure. We observe that at late times the loop expansion
                      does not converge even for large scales (small momenta) well
                      within the linear regime, but exhibits properties compatible
                      with an asymptotic series. We propose a technique to restore
                      the convergence in the limit of small momentum, and use it
                      to obtain a perturbative expansion with improved convergence
                      for momenta in the range where baryonic acoustic
                      oscillations are present. Our results are compared with data
                      from N-body simulations at different redshifts, and we find
                      good agreement within this range.},
