Description
We present a lattice determination of the I = 2 pion scattering length in the large-$N$ limit. This calculation is based on the twisted Eguchi-Kawai formulation of large-$N$ QCD, and employs values of $N$ ranging from 289 up to 1156. Our findings will be compared with Chiral Perturbation Theory predictions and with previous large-$N$ lattice results obtained with standard methods and extrapolating from $N \le 6$.
