Description
I will present the results of a dispersive analysis of the pion vector form factor, which determines the two-pion contribution to the $(g-2)_\mu$ below 1 GeV. As a by-product, both the $P$-wave $\pi \pi$ phase shift as well as the pion charge radius have been determined with higher precision than before.
