We present a new calculation of the $D \rightarrow \pi, l \nu$ semileptonic form factor $f^{D \rightarrow \pi}_+(q^2)$ at $q^2 = 0$ based on HISQ charm and light valence quarks on MILC $N_f = 2 +1$ lattices.

For very complicated multi-exponential fits it can happen that fit results include fake low lying levels (with amplitudes that are consistant with zero) that distort ground state energies and fitting errors. Care is required to watch out for these spurious levels and make sure that fits that exhibit such levels are not trusted. The “sequential fitting” method adopted in this article has been very effective in preventing spurious levels from arising

In reference [ 10 ] the “sequential fitting” method was not employed. Instead the number of exponentials in the three-point correlator ansatz was kept low, at 1 or 2, and only N e x p N{exp} in the two-point correlators increased as in Figs. 1 & 2. Good χ 2 / d o f \chi^{2}/dof were obtained in the simultaneous three- and two-point correlator fits and consistant results for different T T values. We took this as evidence that excited state contributions were suppressed in the three-point correlators compared to in two-point correlators. By simplifying the fit ansatz in this manner, we were able to avoid spurious levels from appearing in [ 10 ]
